Book excerpt: An analysis was made of stable, laminar, free convection, film boiling from isothermal vertical plates and horizontal cylinders surrounded by a saturated liquid, where radiation was only of minor importance. The mathematical techniques of boundary layer theory were used and the boundary layer equations were reduced to ordinary differential equations by means of a transformation similar to those used in free convection and condensation. The equations were solved for: (1) compressible flow with variable specific heat, (2) variable specific heat and density variations considered only in the evaluation of the buoyant force, and (3) the case of constant properties. Numerical results were obtained for: (1) near critical water at 2800 and 3100 psia with wall to liquid temperature differences of 250, 500, and 1000 deg F; (2) for fluids with Prandtl numbers of 2/3, 1, and 2; and (3) for mercury and methanol film boiling at one atmosphere, considering constant properties. The results obtained by assuming constant properties were compared to: (1) the results obtained by considering variable properties, (2) experimental results, and (3) the comparable case of laminar film condensation. It was shown that the method of considering density variations only in the evaluation of the buoyant force is not valid in film boiling. It was also shown that the constant property solutions for heat transfer did not always agree with solutions obtained considering compressible flow and variable specific heat. An approximate analysis of a non-isothermal wall, including the effects of radiation, was presented. It was shown that for high emissivity walls at high temperature, radiation is the controlling factor in film boiling heat transfer.

Book excerpt: Heat and mass transfer is the core science for many industrial processes as well as technical and scientific devices. Automotive, aerospace, power generation (both by conventional and renewable energies), industrial equipment and rotating machinery, materials and chemical processing, and many other industries are requiring heat and mass transfer processes. Since the early studies in the seventeenth and eighteenth centuries, there has been tremendous technical progress and scientific advances in the knowledge of heat and mass transfer, where modeling and simulation developments are increasingly contributing to the current state of the art. Heat and Mass Transfer - Advances in Science and Technology Applications aims at providing researchers and practitioners with a valuable compendium of significant advances in the field.
Book Synopsis Analytical and Experimental Study of Thin Film Evaporation in Heat Pipes by : Hani Sait
Download or read book Analytical and Experimental Study of Thin Film Evaporation in Heat Pipes written by Hani Sait and published by . This book was released on 2004 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the heat flux increases, the thin film evaporation occurring in the evaporator plays a key role in a heat pipe. A better understanding of heat transfer characteristics in the evaporating thin film region will lead to optimizing the thin film region and enhancing the evaporating heat transfer in the heat pipe. An analytical model describing thin film evaporation is developed including the effects of frictional shear stress, surface tension, curvature variation in the thin film interface and disjoining pressure. A unique experimental system was constructed to investigate the effect of heat flux on film thickness in the thin film evaporation region. It has been found that the thin film evaporation is highly affected with the superheat, operation temperature, liquid type, disjoining pressure and thermal conductivity of the liquid. The prediction shows that the interface temperature is not constant at the liquid-vapor interface in the evaporating thin film region. Increasing the thermal conductivity of working fluid leads to directly increasing the heat flux through the evaporating thin film region. The film thickness of interline region was first measured using the experimental setup established in the current investigation. As the input power increases, the film thickness at interline decreases, which is similar to the theoretical prediction. Using this new information on thin film evaporation, a mathematical model predicting the temperature drops occurring in a grooved heat pipe was developed.
