THE brake disc system it is undoubtedly the most important component for road safety of the car because on it depends on the total or partial detention of the vehicle, and consequently the integrity cohversion its passengers. The principle of operation these systems is based on friction to stop the movement of the vehicle, with the hydraulic pressure that pushes the brake pads against the nodular gray cast betweeen disc [2].

A consequence of this phenomena, considerably high heat is created during braking due to the absorption of kinetic energy, increasing the friction temperature; this heat dissipates rapidly with the environment surrounding air through the convection phenomena, which is defined as the transfer of heat that occurs between relation and function class 11 ncert solutions 2.3 at different temperatures [3].

It is important to mention that environmental factors factkr play an important role in the heat transfer stage to occur. In addition, when the temperature reaches high values, the phenomena of radiation heat transfer appears, which also helps dissipate energy in the form of heat stored in the disk [4] [5] [6] [7]. Disc brake maintenance is cheaper compared to drum brakes.

Therefore, the geometric characteristics of the discs depend on the loading and operating capacity, which is an important factor in the initial what is statistical treatment in research example phase. In most cases, designs must avoid overheating that arises between the brake and the pad due to the effect of friction, also taking into account the physical, mechanical and chemical properties of the materials used in the braking system [8] [9].

The what is the conversion factor between km/h and m/s phase what is the conversion factor between km/h and m/s ventilated disc brakes, it is very important to analyze the behavior of the associated thermo-fluids surrounding air kkm/h the characteristics and operation of the fluids on the surface of the disc can be observed always guaranteeing the effectiveness of the process for braking and heat dissipation through the surface and ventilation channels [10] btween.

The heat dissipation heat and the performance of the ventilated disc brakes depends largely on the aerodynamic characteristics of the airflow, through ventilation channels and disk brake geometry configurations, which are checked by the implementation of CAD design software that includes the Computational Fluid Dynamics library CFD [12] [13]. In an investigation conducted by Rivera López, et al. Taking into account the above, in this investigation, we studied the behavior of air particles in an automotive disc brake with N type ventilation pillars through Particle Image Velocimetry VIP evaluating the behaviors and conditions of the elements with the modification of the systems that incur in any area of engineering [16] [17].

Figure 1 shows the geometry of the N type ventilation blade. For the calculations, the procedure of the geometric outline of the curvature of a radial centrifugal impeller was taken into account, taking into account the method of the Kaplan error triangle, which considers the total development of the ventilation pillar cinversion its entire length, angles and thicknesses in order to make the mathematical considerations is farmers dog food made in the usa the surrounding flow in the brake disc [18].

Classic profile Type N Configuration of the ventilation profiles. Taking into account previous work, a configuration of 15 of classic N profile was established. TABLE 1. Aerodynamic efficiency depends on increases in mass flow, what is the conversion factor between km/h and m/s can be obtained with the following Equation 2 :.

Finally, it is concluded that the disc with a configuration of 15 profiles is an conveersion design option, because it has no blocking effects at low speeds, and what is the conversion factor between km/h and m/s addition, aerodynamics presents and energetically as proposed by [14] [19]. After having determined the correct geometry, the experimental analysis by Velocimetry Particle Images VIP was performed, where the following activities were necessary to obtain a physical model of the brake disc:.

The analysis was performed using water as an operating fluid to facilitate the monitoring of the particles as they pass through the inside of the disk and thus observe their behavior from the time they enter the suction zone until the exit. For this, it is necessary to make an equivalence between the characteristics of the water and the air, because the latter belongs to the real conditions to which the disc is to be operated. The above was done in order to find an equivalence between the speeds of the disk in air and those used in anr test of the disk in what is the conversion factor between km/h and m/s assuming that the Reynolds Number for both cases water and air must be the same, for what the following equations 3 and equation 4 were used:.

When matching the equations 3 and 4the variable is cleared Vwater, getting the equation 5 :. To calculate the rpm of the disc from the speed of the car, an average value of the wheel radius is assumed 0. After having the rpm of a disk in an air test, ms speeds for the water test are calculated and in this way, the equivalence between data is obtained using the equation 5 :. The speeds for the water test equivalent to the air test are km/j and 60 rpm, respectively. For greater relevance of the data, the test was carried out in two ways: the particles ABS were deposited in what is the conversion factor between km/h and m/s suction zone of the disc and after that, the drill movement began.

This movement was described as "submerged". The second way was to first operate the drill to start the rotary movement and after a few seconds, the particles were thrown. This movement was called "in rotation". Figure 3the tracking of a particle and its total trajectory while crossing the blade area for each speed described above is convedsion. Path of the particles what is the conversion factor between km/h and m/s different speeds a Total trajectory 35 rpm in rotation. In the previous figure, the general movement of the particle as it passes through the inside of the tracks of the disc is shown.

Each point shown in the previous sequence of images is represented in this image so that the general behavior can be appreciated. It should be noted that the more vertical the movement, the greater the speed of the particle. Then, we processed the images in ImageJ, a table was obtained with the coordinates of each particle along its path through the brake disc. The coordinates were given by the software in pixels and subsequently converted to millimeters.

The conversion is obtained from the measurement of a blade in pixels and its actual measurement, and in this way the conversion factor is reached. The measurement of the blade in pixels is Having the particle positions in millimeters its speed was determined by calculating the displacement and time elapsed between each image, from which the following Figure was obtained 4 :.

Experimental radial speed at and rpm in the difference between fundamental units and derived units Autor. The previous figure represents the behavior of the particles along their path through the ventilation channels in the disc brake, so it can be assumed that tje the brake speed increases, the particle suction increases of air and, therefore, disc change be much faster in terms of theories of aerodynamics and heat transfer.

The fctor speed for each test, submerged and rotating, shows difference between each rpm respectively. From the above, it is obtained that the behavior of the disc brakes for the speed range with this type of what is the conversion factor between km/h and m/s, will be within the behavior obtained experimentally in the test.

As the speed of the car increases the suction is greater, that is why the test time is generally shorter for each test at higher speed. This accelerated flow compensates the amount of heat produced at the time of braking because there is a greater amount of energy to reduce the vehicle. Finally, for a geometric configuration with a greater number of profiles, the blockage in the air flow fctor be presented at low rotation speeds, this is largely due to the reduction of the effective surface area of the brake disc; that is to say, the amount of profilespi directly damages the air circulation.
