Erosion Analysis of Sieve mesh in MULTIPHASE Flow using Ansys or COMSOL
Budget: $50 – $150 USD
Job Title:
CFD Engineer Needed for Multiphase Flow Erosion Analysis of Sieve Mesh (Oil & Gas Application)
Project Overview:
We are conducting a research-based project titled “Erosion Analysis of Sieve Mesh under Multiphase Flow”.
Our goal is to study erosion behavior, material loss, and flow characteristics across a 3D sieve mesh structure when exposed to liquid–solid–gas multiphase flow conditions.
You will be provided with:
A fully prepared 3D CAD model of the sieve mesh and closed test-section geometry (already dimensioned).
Boundary conditions, material properties, and experimental setup data for validation.
Your role will be to perform detailed CFD simulations and provide high-quality results, contour plots, and comparative analysis under varying flow conditions.
Scope of Work / Tasks to Perform:
1. Model Setup
Import the provided 3D CAD model into ANSYS Fluent, COMSOL, or OpenFOAM.
Generate a high-quality mesh (hexa/tetra) with mesh refinement near the sieve mesh region.
Conduct mesh independence and time-step independence tests to ensure accuracy.
2. Physics & Boundary Conditions
Define a multiphase flow model:
Liquid phase: Water (H₂O)
Solid phase: Fine sand particles (size range: 100–500 µm; variable)
Gas phase: Air bubbles (size and volume fraction to vary)
Apply turbulence model: k–ε or k–ω SST, and erosion model: Oka or Finnie (as suitable).
Set inlet velocity range: 1–5 m/s (variable)
Define particle loading fraction: 0.1% – 1%
Specify simulation duration to capture steady-state and transient erosion behavior.
3. Simulation Objectives
Compute erosion rate distribution on the sieve mesh surface.
Identify high-impact regions (erosion hotspots) and visualize particle trajectories.
Analyze the influence of flow velocity, particle size, and concentration on erosion rate.
Evaluate pressure drop, turbulence intensity, and wall shear stress distribution across the mesh.
Compare results for different mesh materials (PLA, ABS, and Stainless Steel 316L – material properties will be provided).
4. Deliverables Required
Full CFD setup files (case and data files).
Simulation report including:
Boundary conditions and setup description
Mesh and independence study
Flow contour plots (velocity, pressure, turbulence kinetic energy)
Erosion contour plots (erosion rate, erosion flux, wear depth)
Particle trajectory animations
Comparison tables for all test conditions
Discussion on dominant erosion mechanisms based on CFD data.
High-resolution visualization renders / videos for presentation and publication use.
Validation summary comparing CFD predictions with experimental observations (you’ll be given reference lab data).
Software Preference
ANSYS Fluent (preferred)
COMSOL Multiphysics / OpenFOAM (optional if experience proven)
Candidate Requirements
2–3+ years of proven CFD experience specifically in multiphase flow simulations (liquid–solid or liquid–gas) in the oil & gas or process engineering sector.
Strong knowledge of erosion and wear modeling, particle tracking (DPM / Eulerian-Lagrangian), and post-processing erosion analysis.
Ability to modify parameters like velocity, particle size, sand fraction, exposure duration, and interpret results physically.
Must provide at least 1–2 samples of previous multiphase or erosion simulation work. (Applications without samples will not be considered.)
Deliverable Timeline
Initial test run and setup validation – within 7 days.
Full set of simulations (with varying parameters) – within 2–3 weeks.
Final report and visual results – within 1 additional week.
What We Will Provide
3D CAD models of sieve mesh and closed test section (STEP/IGES format).
Experimental setup parameters (flow rate, particle properties, density, etc.).
Reference data for erosion validation.
Expected Output Format
Simulation files (.cas, .dat, .msh or equivalent)
Report (Word or PDF, structured with results, plots, and discussion)
All contour and trajectory images in high resolution (PNG/JPEG + video if available)
Preferred Expertise Keywords
CFD, Multiphase Flow, ANSYS Fluent, Erosion Modeling, DPM, Erosion Rate, Sand Particle Flow, Oil and Gas, Wear Prediction, CFD Simulation, Mesh Independence, 316L Stainless Steel, Polymer Erosion, Fluid-Structure Interaction (FSI), Transient Flow, Particle Tracking, Two-Phase Flow, Three-Phase Flow.
Summary for Freelancers:
If you are an experienced CFD engineer with hands-on expertise in multiphase flow, erosion prediction, and oil & gas applications, this is a technically challenging and publication-grade project that requires both simulation accuracy and engineering insight.
Please apply only if you can share sample results from prior multiphase CFD work.
