According to Fig.2band Eq. (19), for a given\({T}_{{{\rm{HS}}},{{{\rm{Latent}}}\), the higher the condensing temperature (i.e.,\({T}_{3}\)), the higher the charging rate, the more heat can be recovered. As a result, the system can operate on the discharging mode wi...
The transfer of heat via conduction within a body takes place according to two distinct mechanisms: transmission via atomic or molecular vibrations and transmission via free electrons. The chapter provides the parallel and series models, since the lowest possible value of the thermal conductivity is ...
A heat exchanger is an equipment unit where heat transfer takes place either via mixing or via heat transfer through a wall. Examples of heat exchangers include shell-and-tube, double pipe, and plate heat exchangers, all referred to as surface heat exchangers. In contrast, the simple mixing ...
The heat transfer fluids flowing through the collectors would be, also, refrigerant of the heat pump units. In an indirect series concept, a liquid-to-liquid heat pump can be assembled as a closed unit and the heat energy from the solar collectors is conveyed to the refrigerant loop of the...
Conjugate heat transfer takes place between the fluid-solid contact surface. The properties fluid and thermal properties of the fluid and the solid are as follows: Table 5 Fluid and Solid Properties Property Fluid Solid Kinematic Viscosity (m2/s) 0.02 NA Thermal Diffusivity (m2/s) 0.02 0.0625...
The heat transfer takes place when the warmer product transfers energy through the flow plates and delivers it to the colder opposing product without mixing the both products. The "herringbone" pattern ensures turbulent flow within the effective area. Furthermore, this pat...
the liquid is drained at the bottom of the tube due to gravity and a thin film of condensate is formed at the top of the tube, leading to an increase in the heat transfer coefficient20. When the flow regime changes to churn, intermittent or annular flows, the liquid phase sporadically ...
For the permeate side, the convection heat transfer takes place in the permeate boundary layer (3.34)Qp=hpTp,m−Tp At the steady state, the overall heat transfer flux through the membrane is given by (3.35)Q=Qf=Qm=Qp (3.36)hfTf−Tf,m=kmδTf,m−Tp,m+J△Hv=hpTp,m−Tp (3.37...
Mainly operating conditions and the configuration of PCM identify a suitable heat storage method; one the top of that the two-phase heat transfer phenomena within a PCM is to be considered (Adebiyi, 1991; De Lucia and Bejan, 1991; Cao and Faghri, 1991). Some researchers suggested that the ...
According to another aspect of the present Invention, a finned heat exchanger coil assembly is provided, wherein heat transfer takes place between a first fluid flowing through a plurality of spaced-apart finned heat transfer tubes and a second fluid flowing outside of the tubes, Each fin has ...
