Introduction: In fluid dynamics, turbulence or turbulent flow is fluid motion characterized by chaotic changes in pressure and flow velocity. It is in contrast to a laminar flow, which occurs when a fluid flows in parallel layers, with no disruption between those layers.  Mixing tee is basically mixing the fluid in…

AIM: Simulate the flow over a cylinder and explain the phenomenon of Karman Vortex Street.    PART-I Simulate the flow with the steady and unsteady case and calculate the Strouhal Number for Re= 100.  PART-II Calculate the coefficient of drag and lift over a cylinder by setting the Reynolds number to 10,100,1000,10000…

Ahmed body and its importance: An important feature of a bluff body flow is that there is a very strong interaction between viscous and inviscid regions. Usually bluff bodies induce flow separation at positions where the velocity at the edge of the boundary layer is higher than the free stream velocity. Prediction of separation…

Introduction: The exhaust manifold is a component that is considered part of an engine's "lungs" because it exhales the gases produced during the combustion process and sends them out the tailpipe to make way for fresh oxygen in each cylinder. Because the more oxygen a motor can burn, the more power it can produce, exhaust…
