Download An Experimental Study of Natural Convection Heat Transfer from a Horizontal Cylinder Array Vertically Aligned to and Confined by a Single Wall and Two Walls Book in PDF, ePub and Kindle
Convection heat transfer was experimentally investigated for two different geometries. One case had three horizontal cylinders in a vertical plane placed between two vertical walls. The second case had three horizontal cylinders in a vertical plane with only one vertical wall. Several different cylinder center-tocenter spacings were investigated. The wall spacings for the two wall and single wall cases were also varied. The cylinders were placed in a still air medium at atmospheric pressure and were maintained at a constant heat flux. The modified Rayleigh number, based on the diameter of the cylinders, ranged from 6.2 x 104 to 1.2 x 106. A scale analysis was performed to predict the relationship between the Nusselt number and the modified Rayleigh number. A standard finite-difference code was employed to show the temperature distribution and velocity vectors distribution around the cylinders. The results showed that there was a maximum heat transfer from each cylinder at a specific wall-array spacing and a specific center-to-center spacing. Comparisons of heat transfer results with a single free cylinder and a free array of horizontal cylinders were made and discussed. Empirical equations were proposed to predict the effects of the experimental parameters on the heat transfer as expressed by the average Nusselt number of each cylinder or the average Nusselt number of the whole array. Flow visualization was accomplished using laser sheets. The resulting studies showed that the presence of a single wall or the asymmetrical placement of the array between the two walls eliminated the presence of the vortices in the spaces between the cylinders and displaced the stagnation points. The asymmetrical placement of the array between two walls created a reversed current between the two walls.

Download Natural Convection from a Horizontal Cylinder Parallel to a Heated Vertical Wall Book in PDF, ePub and Kindle
Heat transfer measurements have been made from a long (L/D = 15) horizontal cylinder in water parallel to a heated vertical wall. The cylinder and wall boundary conditions were isothermal, and they were maintained at equal temperatures. The investigation covered Rayleigh numbers based on cylinder diameter from 400,000 to 10,000,000. The cylinder height above the wall leading edge was set at height to diameter ratios, H/D, of 2.07, 7.44, and 15.50. The horizontal space between the cylinder and wall spanned the range 0.05

Download Natural Convective Heat Transfer from Short Inclined Cylinders Book in PDF, ePub and Kindle
Natural Convective Heat Transfer from Short Inclined Cylinders examines a heat transfer situation of significant, practical importance not adequately dealt with in existing textbooks or in any widely available review papers. Specifically, the book introduces the reader to recent studies of natural convection from short cylinders mounted on a flat insulated base where there is an “exposed” upper surface. The author considers the effects of the cylinder cross-sectional shape, the cylinder inclination angle, and the length-to-cross sectional size of the cylinder. Both numerical and experimental studies are discussed and correlation equations based on the results of these studies are reviewed. This book is ideal for professionals involved with thermal management and related systems, researchers, and graduate students in the field of natural convective heat transfer, instructors in graduate level courses in convective heat transfer.
