Liquid-Solid & Slurry Flow Simulation

Overview

Industrial piping systems often transport abrasive slurries where particle distribution and pressure drop are critical to operational efficiency and equipment longevity. Our expertise in Liquid-Solid flows focuses on predicting phase interactions, solids concentration gradients, and frictional losses in complex geometries.

By utilizing the Eulerian multiphase model, we resolve the interpenetrating continua of both the liquid carrier and the solid dispersed phase, allowing for high-fidelity analysis of momentum exchange and drag.

Case Study: 90° Horizontal Bend Validation

This study validates our modeling approach against the established benchmark: “Flow of mono-dispersed particles through horizontal bend” (Kaushal et al.).

  • Objective: Validate pressure drop and particle distribution in a 90° slurry pipe bend.

  • Physics: Eulerian Two-Phase Model.

  • Key Finding: The simulation accurately captured the centrifugal effects that drive solid particles toward the outer wall of the bend, with pressure drop predictions aligning closely with experimental data.

Validation of Predicted Pressure Drop vs. Experimental Data

The contours illustrate the sand particle volume fraction at the inlet and outlet of the bend. Additionally, the cross-sectional views capture the secondary flow circulation and helical patterns developed as the slurry traverses the 90° geometry.
