On the natural convective heat transfer from a cold horizontal cylinder over an adiabatic surface
A steady two-dimensional laminar free convection heat transfer from a cold horizontal isothermal cylinder located above an adiabatic floor is studied both experimentally and numerically. In the experimental measurements the effects of cylinder distance from horizontal floor to its diameter (L/D) on heat transfer coefficient is studied for Rayleigh numbers of 3×105 and 6×105. Computations are ma...
متن کاملNatural Convection Heat Transfer From Horizontal Cylinders in a Vertical Arra Confined Between Parallel Walls
Laminar natural convection from an array of horizontal isothermal cylinders confined between two vertical walls, at low Rayleigh numbers, is investigated by theoretical and numerical methods. The height of the walls is kept constant, however, number of the cylinders and their spacing, the distance between the walls and Rayleigh number have been varied. The optimal spacing (confining walls) and ...
متن کاملNatural Convection Heat Transfer from two Horizontal Cylinders
Natural convection heat transfer from a single horizontal cylinder and a pair of vertically aligned horizontal cylinders is investigated. Surface heat transfer distributions around the circumference of the cylinders are presented for Rayleigh numbers of 2 x 10, 4 x 10 and 6 x 10 and a range of cylinder spacings of 1.5, 2 and 3 diameters. With a cylinder pairing the lower cylinder is unaffected ...
متن کاملHeat transfer correlations for free convection from upward-facing horizontal rectangular surfaces
A critical review of the heat transfer data available in the literature for free convection from upwardfacing heated rectangular plates is conducted. The review is organized in the form of a table, so as to give the reader the opportunity to compare the dimensionless correlating equations presented, and the conditions under which the heat transfer data were obtained. A comparative survey of the...
