Abstract:Based on the theoretical analysis of a triangular labyrinth screw pump,the 3D flow of clean water inside the pump was simulated with the software FLUENT.The Reynolds time-averaged N-S equation,stand k-ε turbulent model and SIMPLEC algorithm based on unstructured mesh were adopted.The diversification of the main characters of inner flow and the outer characters were obtained.By comparing the results from test and simlation,it is discovered that both performance rules are very consistent,which proves the validity of the calculation model.The results can be used to explain the interior flow field characteristics of the triangular labyrinth screw pump,and will provide some useful references for its design,improvement and optimization.
