WebDec 4, 2024 · For natural convection flows, the surface of the cylinder is maintained by the uniform surface temperature (UST) or the uniform heat flux (UHF) condition. The … WebCFD analysis of laminar and turbulent flow over a circular cylinder has been carried out for different Reynolds number. Coefficients of lift, contours of velocity and pressures are discussed in details. At low Reynolds number (Re=1) flow is steady, and streamline are symmetrical about Y-axis of cylinder. With increasing in Reynolds number, the ...
