Abstract:
In this paper, the entropy generation rates analysis of three-dimensional water jet pump
zones is numerically studied using Computational Fluid Dynamics (CFD) modelling Entropy
generation rate of two different motive fluid velocity, 0.732 m's and 1.465 m/s, at constant
temperature 288.16 K is analysed. Further, the effect of parameters, motive fluid velocity and
temperature are selected and investigated. The CFD results are verified and validated using the
experimental data from literature under no entrainment mode condition. The results show that
the highest entropy generation take place in throat zone around 55 percent of total entropy generation,
which was indicated the highest location of energy loss. Around 99 percent of entropy generation in
water jet pump was produced by dissipation. The effect of motive fluid velocity is more
significant than motive fluid temperature. Increasing velocity increased entropy generation rate
significantly in five zones i.e. throat, convent, chamber, nozzle and diffuser, while increasing
motive fluid temperature influenced decreasing of entropy generation in throat zone only.
