Week 7 - Simulation of a 1D Super-sonic nozzle flow simulation using Macormack Method

INTRODUCTION       A gate valve controls the media's flow by lifting the gate (open) and lowering the gate (closed). A gate valve's distinct feature is the straight-through unobstructed passageway, which induces minimal pressure loss over the valve. The unobstructed bore of a gate valve also allows for a pig's passage…

Conjugate Heat Transfer (CHT) Conjugate heat transfer is defined as the heat transfer between two domains by exchange of thermal energy. For a system the thermal energy available is defined by its temperature and  the movement of thermal energy is defined by its heat flux through the outer walls. Heat transfer in…
