In this manner, the heat link operates with high heat flux without any substantial resistance to liquid flow through a long capillary flow path. By thus replacing almost all of the liquid return wick, with its high resistance to fluid flow, of heat pipes with a low flow resistance liquid ...
as a function of Reynolds number based on the minimum free flow area. This method of data presentation does not permit comparison of surfaces in any simple manner. Soland proposed a method of surface comparison where heat transfer coefficient and friction factor is referred to the base area and...
In this manner, which was first presented by Hubbard and Farkas (1999), the transient surface temperature, Ts is measured by a thermocouple just a few millimeters under the surface (to prevent separation of the thermocouple from the surface). An energy balance (Eq. (2)) is applied to deter...
Clearly, there must be substantial advancements to be made in this field of study [1]. In today's world, wide applications of heat transfer can be found in the construction of the smallest electronic chips such as optoelectronic chips [2] to the cooling of various systems and air ...
A study on MHD Couette flow in a duct filled with porous materials at the thermal entrance and local thermal non-equilibrium effects This investigation primarily focuses on heat transfer to analyze and predict the thermal behaviour of fluids in systems such as heat exchangers, lubrication ... N ...
As heat transfer for flow over a body is inherently complex, the proposed simple means may provide an insight into the mechanism of heat transfer for flow past a body. The behavior of systems involving the motion of small particles relative to fluids in which they are immersed covers a wide...
PROBLEM TO BE SOLVED: To improve the function of a heat-exchanger by preventing refrigerant ununiform flow in respective passages without increasing a pressure loss. ;SOLUTION: This plate type heat-exchanger comprises a plurality of heat transmitting plates which are laminated in a manner to form ...
The fluids are single phase and each a thermal liquid. Neither fluid can switch phase and so, as latent heat is never released, the exchange is strictly one of sensible heat. Heat Transfer Model The block heat transfer model derives from the Effectiveness-NTU method. Heat transfer in the ...
Eiamsa-Ard, S,Thianpong, C,Promvonge, P - 《International Communications in Heat & Mass Transfer》 被引量: 338发表: 2006年 Thermal analysis of heat pipe using self rewetting fluids This paper discuses the use of self rewetting fluids in the heat pipe. In conventional heat pipes, the wor...
5.1.1 Conduction heat transfer Conduction heat transfer is the transfer of heat by means of molecular excitement within a material without bulk motion of the mater. Conduction heat transfer mainly occurs in solids or stationary mediums such as fluids at rest. For instance, transfer of heat in ...
