7. Numerical Investigation of Turbulent Fluid Flow and Heat Transfer in Complex Ducts
Abstract : Th need for a reliable and reasonable accurate turbulence model without specific convergence problem for calculating duct flows in industrial applications has become more evident. In this study a general computational method has been developed for calculating turbulent quantities in any arbitrary three dimensional duct. READ MORE
