(Pressure ratio = Outlet total pressure/ Inlet total pressure) Theory : A centrifugal pump is a mechanical device designed to move a fluid…

Aim : To  Create a 3D model of a flow bench, run a flow analysis and obtain a plot of lift vs mass flow rate. Conduct a Grid dependence test at a particular valve lift and explain the results. To run a parametric sweep to show the effect of valve lift on mass flow rate, once the best grid has been decided.  …

Aim : To Model the flow over a NACA0017 airfoil For the angle of attacks 0,2,4,6,8,10 compare the lift and drag forces Theory : Airfoil is defined as the cross-section of a body that is placed in an airstream in order to generate useful aerodynamic force. Angle of attack is the angle between the oncoming air or relative…

Aim : To simulate the flow over a cylinder for the conditions shown in the video. Calculate the baseline case Reynolds number.  Re = rho*U_inlet*D/mu D = cylinder diameter mu = dynamic viscosity rho = density Run a baseline simulation and then calculate the Reynolds number. Then increase the Reynolds number by a factor…
