Design and Improvement of Convection Cooling for Parallel Plate Duct Flow
Abstract
In this paper a new examinations of the effect of micro channel geometry on high-pressure dispersion and emulsification were carried out. Forced convection heat transfer from arrays of micro channels was regarded for fixed volume and fixed pressure drop constraints. Order of magnitude relationships were advanced for the optimal dimension of a number of original duct shapes containing the parallel plate channel with rectangular, square, rhombus, isosceles right triangle, circular duct and elliptic duct. Using the exact examination technique to generate a rounded expression for the optimal duct shape was advanced for all ducts regarded, where rounded analytical results demonstrate that the optimal shape is the parallel plate channel duct array but with addition a triangular or rectangular duct to the parallel plate. Comparison of the approximate results with exact results from the conventional design illustrates outstanding acceptance for the optimal duct dimensions.
Keywords: micro channel, forced convection, optimal geometry.
