Experimental evaluation of heat transfer coefficients
between radiant ceiling and room.
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:
