Such heat transfer is present in air operated solar collectors. The channel considered is 2m long and 0.1m high. The flow considered is laminar and developing. A constant heat flux of 375W/m2 is applied uniformly to the top plate, whilst the lower plate is considered to be adiabatic. The entrance and exit of the channel are treated as apertures at radiative temperatures of 285K. This Q1 is setup to enable the PHOENICS predictions to be compared with the base case results presented by C H Liu and E M Sparrow in 'Convective-Radiative Interaction in a Parallel Plate Channel - Application to Air-Operated Solar Collectors',J Heat Mass Trans,Vol23 pp 1137-1146. The Q1 contains AUTOPLOT and Viewer macros. ENDDIS DISPLAY The geometry and boundary conditions of this case are identical to those of case R102, but the flow is turbulent with a Reynolds number of 25,000.
