For the design and analysis of their in-house pumps, Hazleton relied on OpenFOAM for computational fluid dynamics (CFD) software and an assortment of tools for computer-aided design (CAD), meshing, and post-processing results. Their simulation workflow was time-consuming and cumbersome, with each step requiring immense manual effort. Project time and cost were further increased by desktop-based computations that did not scale up on-demand and required additional investment in high-performance clusters.
In need of a complementary design and CAE solution, Hazleton turned to Onshape and SimScale. These case studies explore how their cloud-native solution focus enabled Hazleton Pumps to obtain fast and accurate fluid flow and performance assessments for their pump designs.
Parametric Studies for Pump Curve Characterization
Having used OpenFOAM with little success, Hazleton’s Engineering Manager Benjamin van der Walt started investigating Onshape simulation partner, SimScale, in October 2021. Benjamin investigated three pumps using SimScale’s cloud-native technology for rotating machinery, which is capable of solving complex fluid physics for different speed regimes, with or without structural and thermal effects.
This case study will focus on CFD studies for the small- and medium-sized pumps, simulated using an incompressible steady-state approach and a RANS-based turbulence model. The primary objective of the simulations was to accurately calculate and benchmark the performance of the two pump designs.
Case 1: The first pump investigated by Hazleton was a 180 kg, 5.5 kW submersible, as shown below.
