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 ...
Laminar natural convection of Cu-water nanofluid between two horizontal concentric cylinders with radial fins attached to the inner cylinder has been studied numerically. The inner and outer cylinders are considered at constant temperature Ti and To respectively, with Ti>To. The governing equations with the corresponding boundary conditions have been solved by using the finite volume method....
The problem of steady, laminar and incompressible natural convection flow in an octagonalenclosure was studied. In this investigation, two horizontal walls were maintained at a constant hightemperature, two vertical walls were kept at a constant low temperature and all inclined walls wereconsidered adiabatic. The enclosure was assumed to be filled with a Bousinessq fluid. The studyincludes comp...
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...
