In the current CAE approach, since the external air flow is not modelled, it is required to apply non-uniform heat transfer coefficient and heat sink temperature for manifold outer surface.
More dense distribution of heat transfer coefficient with out-of-mesh shown in Figure 11 leads to more heat extraction by oil from gear surface.
This second simulation investigated if it is necessary to generate a separate heat transfer coefficient for the wall thermocouples.
The local growth of the heat transfer coefficient was influenced by the intensifiers due to the reduction of the free cross-sectional area of the channel and because of the increase of the turbulence of the coolant flow.
Tube-side heat transfer coefficient, [h.sub.i] is evaluated from the Gnielinski correlation (Gnielinski, 1976).
Secondly, the forced convection heat transfer coefficient of the synchronous ring friction cone is related to speed, according to formulas (9) and (13).
Local heat transfer coefficient distribution at the blade tip reveals that PSQ performs slightly better than SQ (Figure 9).
where S represents the absorbed solar radiation by the absorber metal and [h.sub.c,ap-c] and [h.sub.r,ap-c] represent convection and radiation heat transfer coefficients between the absorber plate and glass cover, respectively, [h.sub.r,ap-j], represents radiation heat transfer coefficient between the absorbing and jet plates, and [h.sub.cjap-a2] represents convection heat transfer coefficient of the fluid on the absorbing plate.
Thus, by letting the overall heat transfer coefficient be function of mass flow and fouling, a process model is then obtained which is capable of accurately describing the dynamics of the heat exchanger for a wide range of working conditions:
