Experiments on the Transfer Characteristics of a Corrugated Fin and Tube Heat Exchanger Configuration
Journal ArticleDOI
Friction drag resulting from the simultaneous imposed motions of a freestream and its bounding surface
John Abraham,Ephraim M Sparrow +1 more
TL;DR: In this article, the relative velocity between the two media is used in conjunction with the drag-force formula for the dominant of the two motions acting alone, and the results of exact solutions demonstrate that this model is flawed and underpredicts the drag force.
Journal ArticleDOI
Numerical solutions for laminar flow and heat transfer in a periodically converging-diverging tube, with experimental confirmation
TL;DR: In this paper, a solution methodology has been employed that enables the fully developed regime in a duct of periodically varying cross section to be determined without dealing with the entrance region of the duct.
Journal ArticleDOI
Temperature-dependent heat sources or sinks in a stagnation point flow
Ephraim M Sparrow,R. D. Cess +1 more
TL;DR: In this paper, an analytical study has been made to determine the heat transfer characteristics of a stagnation point flow in which there are temperature-dependent heat sources or sinks for a Prandtl number of 0.7.
