- The problem numerically simulates the heat transfer process in brake disks using ANSYS Fluent software.
- We design the 3-D model by the Gambit software.
- We Mesh the model by Gambit software, and the element number equals 32884.
- We have two disks, including the Stationary wall and the Moving wall.
In this project, the heat transfer process in brake disks is simulated, and the simulation results have been investigated using ANSYS Fluent software.
The present model is designed in 3-D using the Gambit. The geometry is related to a brake disk whose temperature increases due to the friction force applied to it because of braking.
The meshing of this present model has been generated by Gambit software. The total cell number is more than 32884.
Brake Disk Methodology
Disks are one of the most widely used components in the industry. The study of the disks’ performance and their rotation’s effect on each other has always been considered by design engineers in mechanics.
The heat generated by the rotation and the friction created at the point where the disks come in contact with each other has adverse effects on the body and reduces their life.
Simulation of brake disks, the study of the phenomenon of heat generated, the heat transfer from the discs to each other, and their surroundings are among the most important issues discussed in the industry.
In this project, ANSYS Fluent software simulates the heat transfer process in brake disks. “Disk2” has a rotating motion with a rotational velocity of approximately 343rpm. The rotating motion of Disk 2 has been applied to it using the moving wall option.
The existing disks have the same temperature equal to 343 K. since “Disk1” is stationary, it will cause “Disk2” to slow down and exert friction.
The Laminar model is used to solve fluid flow equations, and the energy model is also activated to calculate the temperature distribution inside the computational domain.
Brake Disk Conclusion
After the simulation, two- and three-dimensional contours related to pressure, temperature, skin friction coefficient, etc., are obtained.
For instance, as seen in the temperature contour, the fluid and disk temperatures are increased due to the friction imposed on them. Furthermore, in the streamline and velocity vector results, the rotating motion of Disk 2 is visible.
