Aim: Part 1: Simulate the flow with the steady and unsteady case and calculate the Strouhal Number for Re= 100 Part 2: a) Calculate the coefficient of drag and lift over a cylinder by setting the Reynolds number to 10,100,1000,10000 & 100000. (Run with steady solver) b) Discuss the effect of Reynolds number on…

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…
