Aim:- To perform analysis on cyclone separator and calculate the separation efficiency and pressure drop.   Objective:- To write a few words about any four empirical models used to calculate the cyclone separator efficiency.  To perform an analysis on a given cyclone separator model by varying the particle…

Q1. Ans: The Ahmed body was described originally by S. R. Ahmed in 1984. The Ahmed body is a generic car body (a simplified vehicle model). Although it has a simple shape, the Ahmed body allows us to capture characteristic features that are relevant to organisations in the automobile…

Aim : To do various simulations on the flow over a cyinder at various reynolds number  Software used : Ansys 2020 R1 Objectives:    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…

Software used: ANSYS FLUENT  Given: Two versions of the mixing tee are given. One of them is longer than the other. Steady-state simulations…

Q1. ANS The contemporary conjugate convective heat transfer model was developed after computers came into wide use in order to substitute the actual relation of proportionality of heat flux to temperature difference with heat transfer coefficient which was the only tool in theoretical heat convection since…

Q1 Ans: Some of the models are: Richtmyer–Meshkov instability: - The Richtmyer–Meshkov instability (RMI) occurs when two fluids of different density are impulsively accelerated. Normally this is by the passage of a shockwave. The development of the instability begins with small amplitude perturbations…
