This book was released on 1971 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural convection heat transfer in air between two vertical plates 38 by 24 inches was investigated in this work with spacings between the plates of 0.625, 1.0 and 1.75 inches. One plate was isothermal and the other adiabatic. To measure the point velocities in the air layer a very thin quartz fiber 0.0005 in. in diameter was used. An iron- constantan thermocouple 0.001 in. in diameter was used for local temperature measurement. Velocity and temperature profiles were obtained at several positions along the plate for each spacing between the plates. An equation in the form Nu[subscript x] = 0. 348 (Gr[subscript x] (x/W))0[superscript .]241 best describes the local heat transfer characteristics for this study.
