Journal ArticleDOI
A review of mass transfer measurements using naphthalene sublimation
Richard J Goldstein,H. H. Cho +1 more
TL;DR: The naphthalene sublimation method can be used to study mass and heat transfer with confidence for a variety of applications, but with certain restrictions as discussed by the authors, such as high-velocity flows.
Journal ArticleDOI
Convective heat transfer in periodic wavy passages
G. Wang,Surya Pratap Vanka +1 more
TL;DR: In this article, the authors studied the rate of heat transfer for flow through a periodic array of wavy passages with an accurate numerical scheme, and observed that self-sustained oscillations lead to the destabilization of laminar thermal boundary layers, replenish the nearwall fluid with the fluid in the core region, and thus provide a natural mechanism of heat and mass transfer enhancement.
Journal ArticleDOI
Heat transfer and pressure drop in corrugated channels
TL;DR: In this paper, the effects of channel spacing and phase shift variations on convective heat transfer and pressure drop characteristics of flow in corrugated channels have been experimentally investigated, and the results showed a significant heat transfer enhancement accompanied by increased pressure drop penalty.
Journal ArticleDOI
Experimental investigation for optimization of design parameters in a rectangular duct with plate-fins heat exchanger by Taguchi method
TL;DR: In this paper, the authors presented the determination of optimum values of the design parameters in a heat exchanger with a rectangular duct by using Taguchi method, and the experimental results validated the suitability of the proposed approach.
Journal ArticleDOI
Vortex instability in a diverging–converging channel
TL;DR: In this paper, it is shown that under certain conditions the divergence-convergence of the channel leads to the formation of a secondary flow in the form of streamwise vortices.
