Abstract The 3-d turbulent flow in the impellers of double-channel pump issimulated in this paper. By using the time-averaged N-S equations and the k-eturbulent model modified to consider the curvature and rotation, applying SIMPLE-Calgorithm to make pressure-velocity correction equation, the calculation is carriedout with Body-fitted Coordinated grid. The calculated velocity and pressuredistributions of the turbulent flow in double-channel pumps are given for the firsttime, which will be supportive to the optimal design and performance prediction ofdouble-channel pumps on the basis of flow field simulation.
