Parallel computation of thermohydraulic problem is examined using four transputers in array. Geometric and algorithmic parallelisms are tested with Parallel FORTRAN for two-dimensional thermal conduction and cavity flow problems. The speedup ratio and efficiency of the parallel computations are measured in terms of the number of transputers, mesh size and time steps. The results obtained show the geometric parallelism to be more effective than the algorithmic one. This is because the former requires data communication only at domain boundaries while the latter for all of the mesh points. The efficiency of the parallel computation is evaluated for the two-dimensional thermal conduction and compared with the measured values. The speedup ratio and efficiency for a very large parallelism are also estimated.
