Explain the most efficient flow regime for heat transfer

Reference no: EM13226824

A number of geometries were initially investigated for the design of radioactive fuels suitable for use in a nuclear reactor, eventually converging on the use of cylindrical fuel rods for commercial energy generation applications. However other geometries have been tested, including slabs. Consider a uranium slab that is 0.5m long, 0.30m wide, 0.002 m thick. this slab is maintained at a temperature of 1000 deg C as a result of the fission process, heat which is transferred to a surrounding fluid for power generation. Fluid is passed over the surface, parallel to the slab.

a) what is the minimum velocity that the fluid should travel at in order to remain in the most efficient flow regime for heat transfer if the fluid is i)water ii)paraffin oil iii) helium (1 atm) in each case Tinfinity= 75 deg

b)what is the rate of heat tranfer for the situations in part a?
