Featured Case Studies
Parabolic-shaped Shelter Design Analysis
Simulation of Air Heater Shell Temperature
Effects of Mist & Jet Cross-Section on Heat Transfer for a Confined Air Jet Impinging on a Flat Plate
Convective heat transfer to an impinging air jet is known to yield high local and area-averaged Nusselt numbers. Our engineers simulate this heat transfer over a wide range of study parameters, including Reynolds number and mist mass fraction, and three jet shapes: circular, half circuit, and quarter circuit by using ANSYS CFX.
Simulations conducted during our CFD consulting services show that when compared with air only, mist provides higher heat-transfer enhancements for the first two shapes but is insignificant for the third.
The area-average Nusselt number is higher by ~100% for the half-circuit jet than for the circular jet for both single-phase air and mist. With 0.5% mist, the area average Nusselt number of the circular jet is enhanced by 41% at Reynolds number 10000.
