NTU is the number of transfer units. UOverall is the overall heat transfer coefficient between fluid 1 and fluid 2. ROverall is the overall thermal resistance between fluid 1 and fluid 2. AHeat is aggregate area of the primary and secondary, or finned, heat transfer surfaces. The thermal...
°C, Cp,a the specific heat of air, NTUe the number of heat transfer units, dei and the dry air inlet and time-averaged outlet humidity ratios in kg kg−1, respectively, γ the heat of condensation in kJ kg−1, and is the time-averaged water uptake rate in kg kg−1 s−1...
The units of k are W/m K and the dimensions are [M L T−2 θ−1]. The thermal conductivity can be related to the microscopic behavior of the substance. The coupling of the Fourier equation, also called the constitutive equation for heat conduction, with the first law of ...
whereQActthe actual heat transfer rate,QMaxis the ideal heat transfer rate, andQActis the fraction of the ideal rate actually observed in a real heat exchanger encumbered with losses. The fraction is the heat exchanger effectiveness, and it is a function of the number of transfer units, or NT...
Heat Transfer Thermal Liquid 1 mass flow rate vector, mdot1— Mass flow rate of thermal liquid 1 at each breakpoint in lookup table for specific heat dissipation table numerical array with units of mass over time Thermal Liquid 2 mass flow rate vector, mdot2— Mass flow rate of thermal liq...
where NTU=UA/(m˙cCpc)=(Tci−Tco)/ΔTlm is the number of transfer units. Eq. (5.24) relates the value of NTU with temperature. Heat lost by the charging fluid will be gained by the phase changing material qs qc=qs=ms[Cps(Tl−Tsi)+ΔHm+Cpl(Tsh−Th)] where ΔHm is the he...
Plate heat exchangers are designed to optimize heat transfer, because the corrugated plates provide by far the greatest surface area through which the heat can be drawn from one gas or liquid to the other.The units also have a flexible design and are easy to service and ...
