Two approaches to predict the average or representative heat-transfer coefficient for a long, horizontal fin cooled by natural convection and radiation have been presented鈥攖he integration method and the heat-balance method. Both approaches make use of a numerically determined temperature distribution ...
TARGET: to map the convective heat transfer coefficient (H.T.C., h_cell, [W/m2 K]), without using the energy equation (the "cold" approximation I mean) using a cell by cell formulation, along the frontier of a 3D very complex geometry (many characteristic lengths, confined domain, forc...
This paper presents calculated results for the surface temperature rise and free convection heat transfer coefficient in the case of a vertically oriented pot-core inductor or transformer for which the total loss is known. The average surface temperature rise and convection heat transfer coefficient are...
The constant of proportionality h is termed the convection heat-transfer coefficient. Other terms describing h include film coefficient and film conductance. Variables needed to parameterize free convection are: Definition of Symbols Independent Parameters for the Fluid Quantity Symbol Units bulk temper...
A Study of the measuring method and error of coefficient of heat transfer by convection for the interior walls have been studied using the appratus for measuring the air temperature near the surface of a wall. Quantity of heat flow by covection are assessed from multipling the air temperature ...
The convection heat transfer coefficient of coolant within the grinding zone has been estimated using hydrodynamic and thermal modeling.(磨削区冷却液的热对流系数已由流体动力学和传热学模型估算得到。) The outer layers form a convection zone where the gas material transports energy primarily through phys...
The heat transfer coefficient were then calculated for forced convection for several Reynolds number (4555-18222).The study covered free convection impact for values of Rayleigh number ranging between (1069-3321). Imperical relationships were obtained for all cases of forced and free convection and ...
The results show that the isosceles' triangular cavity and the nanoparticles' distribution and size play an important role in heat transfer. Compared to the operating fluid behavior, the behavior of the nanofluid has a lower friction coefficient. The higher the coefficient of friction in the cavity...
affect the heat transfer rate from the porous plate. in general, suction tends to increase the skin friction and heat transfer coefficient, whereas injection acts in the opposite manner. suction can be used as controlling parameter in boundary layer separation, providing a method to manage and pos...
