Web1. Ratio of inertia force to viscous force is known as a) Grashof number b) Reynolds number c) Peclet number d) Stanton number View Answer 2. The ratio of heat flow rate by convection to flow rate by conduction is known as a) Stanton number b) Graetz number c) Fourier number d) Peclet number View Answer 3. 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 Number You see this number and you should think of natural or free convection. The Grashof number is the ratio of buoyancy forces to the viscous forces. In natural convection the Grashof number plays the same role the is played by the Reynolds number in forced convection. WebThis problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. See Answer. Question: 5) Number is to Convection …
WebThe Grashof number and the square of the Reynolds number are plotted as functions of the velocity of air as it passes over a flat plate. The yellow area represents the region where and free convection dominates heat transfer. The blue area represents the region where and forced convection dominates heat transfer. WebFeb 2, 2011 · In the region of a strong effect of free convection the mode of thermal turbulent convection with the dependence of the Nusselt number on the Grashof number, characteristic to turbulent free convection Nu = A (Pr)Gr 1/4 and excluding the effect of a geometry parameter on heat transfer, is established.
