Aim: The aim of this challenge is to perform steady state simulation on an Ahmed body with incoming air at 25m/s velocity. Introduction: The Ahmed Body was first created by S.R. Ahmed in his research “Some Salient Features of the Time-Averaged Ground Vehicle Wake” in 1984. Since then, it has become a benchmark…

Introduction: Conjugate Heat Transfer (CHT) is the process of thermal energy exchange when solid and fluid domain interacts with each other. i.e. conjugate heat transfer corresponds with the combination of heat transfer in solids and fluids. In solids, conduction often dominates whereas, in fluids, convection usually dominates.…

Introduction: Rayleigh-Taylor instability (RTI) is the interpenetration of process that occurs whenever a light fluid pushes on a heavy fluid. It is a dynamic process whereby the two fluids seek to reduce their combined potential energy by rupturing plane between them. The ensuing turbulence and mixing has far-reaching…

Aim: Perform a steady-state conjugate heat transfer analysis on a model of a graphics card. You can use appropriate materials of your choice for the simulation. Make sure to properly define the correct solid and fluid zones. Objectives: Run the simulation by varying the velocity from 1m/sec to 5m/sec for at least 3 velocities…
