The heat transfer coefficient has SI units in watts per squared meter kelvin : W / ( m 2 K ).
22.
A high degree of turbulence can be obtained at low flow rates and high heat transfer coefficient can then be achieved.
23.
This separation induces considerable fluid mixing near the surface, substantially increasing the convective heat transfer coefficient and the heat flux.
24.
Forced Circulation Evaporators have high velocity liquid velocity and therefore a high turbulence this ergo equates to high heat transfer coefficients.
25.
Heat transfer coefficients measured in the MSRE agreed with conventional design calculations and did not change over the life of the reactor.
26.
They also observed that the maximum heat transfer coefficient occurs where the flow reattached after initially separating due to the roughness elements.
27.
The overall heat transfer coefficient takes into account the individual heat transfer coefficients of each stream and the resistance of the pipe material.
28.
The overall heat transfer coefficient takes into account the individual heat transfer coefficients of each stream and the resistance of the pipe material.
29.
They also produce turbulent conditions at low flow rates, increasing the heat transfer coefficient, and hence the rate of heat transfer.
30.
Experimental assessment of the heat transfer coefficient poses some challenges especially when small fluxes are to be measured ( e . g . ).
