This paper seeks to predict the performance of the side channel pump by considering the influences of different wrapping angles. Firstly, three pump cases 1, 2 and 3 are modeled with wrapping angles 15°, 30° and 45°, respectively. Secondly, different physical parameters comprising exchanged mass flow, pressure and velocity distributions are plotted at the best efficiency point (QBEP) to analyze the internal flow characteristics. Since the flow exchange times depend on the size of the wrapping angle, the size of the wrapping angle has significant effects on the pump head performance. Case 1 with the smallest wrapping angle recorded the largest head improvement at all operating conditions compared to case 2 and case 3. Case 1 at QBEP attained a head coefficient increase of about 9.8% and 38.6% compared to that of case 2 and case 3, respectively. However, the size of the wrapping angle had a slight effect on the pump efficiency; thus, case 1 still predicted a marginal increase in efficiency compared to case 2 and case 3 at all operating conditions. Lastly, the numerical simulations were validated with experimental data after manufacturing pump case 2.

“…The pump is mainly made up of the inlet pipe, radial impeller blades, circular side channel and outlet pipe. The suction side of the impeller is profiled in an isosceles-triangular form with the suction angle of 30 • [24,25]. The inlet pipe is separated by the interrupter from outlet pipe to prevent reverse flow.…”

Summary The side channel pump, which is a common energy conversion equipment, has undergone high developmental trends and has become very popular in recent times because of its wide applications in many fields. The side channel pump is a type of regenerative pump that plays a role in between the centrifugal pump and the positive displacement pump. This kind of pump delivers a high head at relatively small flows compared with other axial and centrifugal pumps even though it requires a low specific speed. Depending on the number of impellers used, the side channel pump can be single‐stage or multistage. This paper first focuses on the physical principle behind the internal flow characteristics illustrating the complex flow and the energy from the blade to the fluid and the side channel inside the pump. Further discussions disclosed that the hydraulic performance of the pump greatly depends on the variations of the geometrical parameters. This review draws conclusion that enhancement of the computational modeling techniques will improve the efficiency of this pump, thereby broadening its applications.

“…Fleder and Böhle [21] conducted numerical and experimental studies on different geometrical conditions such as blade length, blade width and side channel height to analyze the internal flow characteristics and its influence on the hydraulic performance of a side channel pump. Recently, Zhang et al [22,23] put forward that the greater blade suction angle, the higher the head performance. Even though, the blade suction angle had a minimal effect on the efficiency, the blades profiled with suction angle 30 • produced optimal performance compared to 10 • and 20 • .…”

Side channel pumps are important machines for handling toxic, explosive or other dangerous liquids in various engineering processes. However, the operational reliability of these pumps is directly affected by the intensity of the pressure and velocity fluctuations, thus the flow fluctuations existing within the pump cannot be neglected because of their direct influence on the noise, vibration and harshness performance. Therefore, describing precisely the zones of highly unsteady and turbulent flow fields is a key research topic. Moreover, the size of the wrapping angle strongly affects the levels of pressure and velocity fluctuations, thus numerical calculations of the pressure and velocity fluctuation intensities in side channel pump models with different wrapping angles were conducted in this work. The results indicated that the pressure fluctuation coefficient increased gradually from the inflow to the outflow. At the interrupter, the flow experienced the most irregular flow patterns in the pump. The flow at the inflow region in both the impeller and side channel passage rendered weak pressure fluctuation intensities. All three pump cases operated with 24 blades but after one complete circulatory cycle, cases 1, 2 and 3 revealed 21, 20 and 19 regular pressure fluctuations respectively in the impeller flow passage. On the other hand, the side channel flow passage rather produced 24 regular pressure fluctuations. Furthermore, the main frequency harmonic excitations for all studied monitoring points in the impeller and side channel flow passages of the three pump cases occurred at 600 Hz (24 × fn), 1200 Hz (48 × fn), and 1800 Hz (72 × fn). For this reason, exchanged flow times between the impeller and side channel is mainly responsible for the pressure fluctuation which subsequently affects the noise and vibration generation in the side channel pump. Hence, the results could be used as a reference for Noise-Vibration-Harshness (NVH) study in turbomachinery especially modifying the side channel pump in order to improve the operational reliabilities for many engineering processes.
