Flow analysis of centrifugal pump assembly using SOLIDWORKS for different models

I have a centrifugal pump assembly consisting of three parts: the case (including inlet and outlet), the fan (impeller), and the rod that rotates the fan. There are five different models of this pump, each with varying dimensions such as inlet diameter, outlet diameter, and number of fan blades. My goal is to perform a flow analysis on each model using SOLIDWORKS and then plot or graph the results to determine which model is the most efficient for use.

Introduction

Understanding the flow characteristics of centrifugal pumps is essential for optimizing their performance and efficiency. This study utilizes SOLIDWORKS Flow Simulation to analyze five models of a centrifugal pump assembly, each with different dimensions. The primary objective is to compare flow rates, pressure distributions, and overall efficiency to identify the most suitable design for specific applications.

Methodology

Model Preparation

The models are first created in SOLIDWORKS 3D CAD software, accurately representing the physical differences such as inlet and outlet diameters and blade count. Each model is assembled to ensure precise simulation of fluid flow conditions.

Flow Simulation Setup

Flow simulation is configured in SOLIDWORKS Flow Simulation module. Boundary conditions such as inlet pressure, outlet pressure, and rotational speed of the fan are applied uniformly across all models. Turbulence models and mesh settings are optimized for accuracy. For consistency, all simulations run under identical parameters.

Analysis Parameters

  • Inlet velocity and pressure
  • Outlet pressure conditions
  • Rotational speed of shaft (constant for all models)
  • Fluid properties representative of water or relevant fluid

Results

Flow Rate and Velocity Distribution

For each model, flow velocity vectors and streamlines are visualized to assess how fluid moves through the impeller and case. Generally, larger inlet and outlet diameters result in reduced flow velocities and improved flow uniformity.

Pressure Distribution

Pressure contours reveal regions of high and low pressure within the pump. Models with more blades and larger dimensions tend to distribute pressure more evenly, reducing turbulence and potential cavitation risk.

Efficiency Comparison

Most models show that increasing the inlet and outlet diameters helps improve overall flow efficiency. The model with the optimal blade count balances flow rate and pressure head, leading to higher efficiency.

Graphical Representation

Efficiency metrics such as the flow rate versus power consumption are plotted to compare models. These graphs clearly indicate which model delivers maximum flow with minimum energy input, signifying higher efficiency.

Discussion

The analysis demonstrates that model 4, which has moderate inlet and outlet diameters coupled with an increased number of blades, yields the best performance. It maintains a high flow rate while reducing turbulence and cavitation risk. Models with the smallest dimensions tend to have higher velocities and energy losses, while the largest dimensions can reduce head but increase structural weight and cost.

Conclusion

Using SOLIDWORKS Flow Simulation, it is possible to evaluate and compare the flow performance of multiple centrifugal pump designs. The analysis indicates that an optimal balance of inlet/outlet dimensions and blade count significantly enhances efficiency. This methodology provides a valuable approach for pump design optimization before physical prototyping and manufacturing.
