Week 6: Conjugate Heat Transfer Simulation

Objective To apply Reynolds decomposition to the Navier Stokes equation and to determine the expression for Reynolds stress.   Navier Stokes Equations The movement of fluid in the physical domain is driven by various properties. For the purpose of bringing the behaviour of fluid flow to light and developing a mathematical…

Objective To set up a transient simulation in a shock tube using Converge CFD, where one side is filled with high pressure nitrogen and the other side with low pressure oxygen separated by a diaphragm, and to view the flow results.   Theory A shock tube is a device used for studying shock waves. Initially, a diaphragm…

Objective  To simulate the conjugate heat transfer flow with various grid sizes and super cycle time values and illustrate the results.   Theory CHT Analysis Conjugate heat transfer (CHT) analysis can accurate predict heat transfer by simultaneously solving all the relevant solid and flow field heat transfer…

Objective To simulate the Prandtl Meyer shock flow and analyse the effects of various sub grid criteria sizes on the results of subsonic and supersonic inlet velocities.   Shock wave A shock wave is a type of propogating disturbance that moves faster than the local speed of sound in the medium. Like an ordinary wave,…
