Evaluating the Performance of a Low Reynold’s Number Turbulence Model for Describing Mixed-flow Airspeed and Temperature Distributions
نویسندگان
چکیده
The effectiveness of a three-dimensional mixed-flow turbulence model describing airspeed and temperature distribution in a laboratory scale slot-ventilated chamber was evaluated. Airspeed and temperature profiles were investigated near the inlet jet region and along an axial line extending from the inlet. The observed jet-floor impingement location was accurately predicted^ with a maximum difference of 18% (Ax/L = 0.18), Average building temperature as a Junction of the inlet corrected Archimedes Number was also accurately predicted. Differences between measured and predicted values were 5,0% or less. Airspeed and temperature profiles near the inlet and along an axial line from the inlet were compared and large localized errors were found.

Numerical Predictions of Turbulent Mixed Convection Heat Transfer to Supercritical Fluids Using Various Low Reynolds Number k-e Turbulence Models
There are a number of systems in which supercritical cryogenic fluids are used as coolants or propellant fluids. In some modern military aircraft, the fuel is pressurized above its critical point and used as a coolant to remove heat from the aircraft engine. Accurate prediction of heat transfer coefficients to turbulent flows of supercritical fluids is essential in design of such systems. One o...

In this study, turbulent compressible gas flow in a rectangular micro-channel is numerically investigated. The gas flow assumed to be in the subsonic regime up to Mach number about 0.7. Five low and high Reynolds number RANS turbulence models are used for modeling the turbulent flow. Two types of mesh are generated depending on the employed turbulence model. The computations are performed for R...
