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 Reynolds number is based on open flow area, as though the fins were ...
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 ...
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...
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...
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 ...
The Heat Exchanger (TL-TL) block models the complementary cooling and heating of fluids held briefly in thermal contact across a thin conductive wall. The wall can store heat in its bounds, adding to the heat transfer a slight transient delay that scales in proportion to its thermal mass. Th...
EFFECTS OF GROOVE ARRANGEMENTS ON THE FLOW PATTERN AND HEAT TRANSFER IN A HEAT EXCHANGER TUBE WITH DISCRETE GROOVES In this paper, we use a Stereoscopic Particle Image Velocimetry (SPIV) system to measure the flow field of a circular tube fitted with central slant rods i... N Zheng,L Peng...
An increase in the heat transfer surface area leads to an increase in the length of the GHE, and this leads to an increase in the hydraulic resistance when pumping the HTF. It is also possible to retain the length of the pipes, but at the same time change the configuration to reduce ...
This study presents an experimental and numerical investigation into the efficiency of a two-stage heat recovery–storage system for reducing the thermal energy losses in the industry. The system is designed to recover and store waste thermal energy from residual fluids using heat pipes for recovery...
Disclosed is apparatus and a system thereof for reclaiming heat through the transfer of heat from normally waste hot gases to a liquid medium, usually water, and redistributing the heat by way of the
