RISNumerical Investigation of Natural Convection Heat Transfer From a Stack of Horizontal Cylinders
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Natural convection heat transfer from horizontal solid cylinders has been studied numerically by varying the Rayleigh number in the range of (104≤Ra≤108) and (1010≤Ra≤1013) for both laminar and turbulent flows, respectively. ...
