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 ... WebGrashof's theorem states that a four-bar mechanism has at least one revolving link if s + l = p + q (5-1) and all three mobile links will rock if s + l > p + q (5-2) The inequality 5-1 is …
