heat transferexact solutionThis study describes ciliary motion on the transport of fluids in human body with heat transfer. The mathematical model of the flow of a Jeffrey fluid in a tube of finite length is considered due to metachronal wave of cilia motion. Flow equations have been modeled ...
The dissimilarity between the momentum and heat transfer due to streamwise traveling wave-like wall deformation in turbulent channel flows is investigated through direct numerical simulations. The flow rate is kept constant, and the bulk Reynolds number is Re= 5600. A constant temperature difference co...
Conduction heat transfer is the transfer of heat through matter (i.e., solids, liquids, or gases) without bulk motion of the matter. In another ward, conduction is the transfer of energy from the more energetic to less energetic particles of a substance due to interaction between the particle...
Also, the rate of heat transfer varies with time due to the change in the internal energy of the system. Unsteady-state conditions are a predecessor to steady-state conditions. Heat can be transferred by three different mechanisms: conduction, convection, and radiation. Heat conduction is the ...

2, at G = 50 kg m−2 s−1 the heat transfer coefficient during normal gravity was about 33–56% higher than the one measured in microgravity conditions, while at G = 30 kg m−2 s−1 the heat transfer enhancement due to the gravity effect varied from 52% to...
Microfluid devices have a significant advantage in heat transfer due to their extremely high surface area-to-volume ratio, which naturally attracts the attention of researchers in the field of heat transfer. In 1981, Tuckerman et al. [25] first proposed the concept of microchannel heat sinks and...
Increase in both the amplitude and the frequency of the pulsations had a significant effect on the heat transfer enhancement. Heat transfer enhancement is mainly observed in the front and back of the cylinder. At a steady flow in these areas, heat transfer is minimal due to the weak ...
Radiation heat transfer is possible through vacuum, gas or liquid. In the vacuum the heat will be fully transferred, in gas there will be an attenuation due to the absorption and reflection by the gas molecules, the attenuation is even higher in liquids as they are more dense than gas. In...
