Research ArticleOpen accessPhrase in the titleEffect of Geometry and Dimensionless Parameters on Heat Transfer Characteristics of a Closed–end Oscillating Heat-pipe at Vertical PositionS. Rittidech, K. PhalasinThis heat transfer characteristics of a closed-end oscillating heat-pipe (CEOHP) depend on a number of parameters. They are the number of turns, inner diameter of the tube, aspect ratio and the dimensionless parameters of heat transfer. The CEOHPs used to employ a copper tube with inner diameter of 0.66, 1.09 and 2.03 mm. The lengths of the evaporator, adiabatic and … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 6,642 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleExplicit Finite Difference Solution of Heat Transfer Problems of Fish Packages in PrecoolingA. S. Mokhtar, K. A. Abbas, M.M.H. Megat Ahmad et al.The present work aims at finding an optimized explicit finite difference scheme for the solution of problems involving pure heat transfer from the surfaces of Pangasius Sutchi fish samples suddenly exposed to a cooling environment. Regular shaped packages in the form of an infinite slab were considered and a generalized mathematical model was written in dimensionless form.
