Combustion:     Thermal NOx Thermal  is produced during the combustion process when nitrogen and oxygen are present at elevated temperatures. Prompt NOx Prompt NOx is formed from molecular nitrogen in the air combining with fuel in fuel-rich conditions which exist, to some extent, in all combustion…

Aim: To perform a parametric study on the gate valve simulation by setting the opening from 10 % to 80%. Obtain the mass flow rates at the outlet for each design point. Calculate the flow coefficient and flow factor for each opening and plot the graph. Discuss the results of the mass flow rate and flow coefficient. Geometry…

Cyclone separators Cyclone separators  are separation devices (dry scrubbers) that use the principle of inertia to remove particulate matter from flue gases. Cyclone separators is one of many air pollution control devices known as precleaners since they generally remove larger pieces of particulate matter. Cyclone…

Problem Statement: To Perform a steady-state conjugate heat transfer analysis on a model of a graphics card. Run the simulation by varying the velocity from 1m/sec to 5m/sec for at least 3 velocities and discuss the results. Find out the maximum temperature and heat transfer coefficient attained by the processor. Prove…
