This book was released on 1996-06-01 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of the current research was to investigate the effects of reducing screen thickness on the volume and compactness factor of stacked, wire-screen regenerators. An improved transient step-change method was devised which integrated experimental data with a numerical model of the flow to determine the heat transfer coefficient and friction factor. The improvements to the approach are: (1) the measured inlet temperature trace is used, (2) the heat transfer coefficient is based on a parameter called the sponge effect delay time, and (3) the important effect of the tube surrounding the matrix is included in the numerical model. The data show that the heat transfer is the same for reduced thickness screens as it is for unrolled screens once the decrease in surface area caused by rolling the screens is taken into account. However, the friction factor increases, particularly for a 50% reduction in screen thickness. Consequently, the ratio of Colburn factor to friction factor, the compactness factor, decreases as the thickness of the screens decrease. The effectiveness of the regenerators is also adversely affected by the rolling.

Available in PDF, EPUB and Kindle. Book excerpt: "The term regenerator is widely used to define any type of heat exchanger in which the heat is alternately stored and removed ... The present investigation is concerned with the calculation of the characteristics of the "single-blow", tubular regenerative heater, its dimensions and performance. In the analysis in this thesis, the heat is considered to be stored in bundles of tubes initially preheated by hot gases flowing through the heater and subsequently cooled by the flow of air. This paper makes no attempt to deal with the effects of radiation from the outer row of tubes to the heater shell"--Introduction, leaves 1-3.

This book was released on 1993 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study investigated the effect on heat transfer and friction characteristics for screen regenerative heat exchangers with the screen thickness reduced by rolling. The experiments were performed on 250 and 325 mesh, 304 stainless steel screen using helium gas. Reynolds numbers, based on hydraulic radius, Re, were between 10 and 100. Both the Colburn factor, StPr(2/ 3), and friction factor, f, decreased as the screen thickness was reduced. A correlation was found for predicting friction factor, f. The drag coefficient per screen remained nearly unchanged for thicknesses reduced not more than 30 percent. The decrease in Colburn factor was significant for Re less than 40. For Re between 40 and 100 the decrease in Colburn factor was less than the experimental uncertainty.
