Engr. Zartash I.

I am a Computational Fluid Dynamics (CFD) Engineer and R&D Consultant specializing in advanced numerical simulation, multiphysics modeling, and physics-based engineering analysis. I help researchers, startups, and engineering teams transform complex fluid-flow and transport problems into reliable, interpretable, and decision-ready simulation results.

My approach goes beyond simply generating CFD contours. I focus on understanding the underlying physics, selecting appropriate mathematical and numerical models, achieving reliable convergence, assessing mesh independence, validating results where reference data are available, and translating simulation outputs into meaningful engineering conclusions.

My core expertise includes:

• ANSYS Fluent & ANSYS CFX — advanced CFD, turbulence, multiphase and reacting flows
• OpenFOAM & SU2 — customized CFD modeling, external/internal flows and numerical simulations
• MFiX — gas-solid multiphase flow and fluidized-bed reactor modeling
• COMSOL Multiphysics — coupled multiphysics, transport phenomena and electrochemical systems
• Aerodynamics — NACA airfoils, vehicle aerodynamics, circular-cylinder flow, drag/lift and flow-field analysis
• Heat Transfer — conjugate heat transfer (CHT), thermal-fluid analysis and heat exchanger performance
• Mass Transfer & Chemical Engineering — reaction engineering, species transport, porous media and process systems
• Multiphase Flow — fluidized beds, particle-fluid interactions, phase distribution and reactor hydrodynamics
• Electrochemical Modeling — PVMR and coupled transport/electrochemical systems
• MATLAB & Python — automation, numerical modeling, optimization, custom calculations and advanced post-processing

I can support the complete CFD workflow—from geometry preparation and computational-domain development through meshing, boundary-condition definition, solver configuration, convergence monitoring, post-processing, validation, and technical reporting.

My work is particularly suited to projects requiring more than a standard simulation: research studies, prototype development, design optimization, performance improvement, troubleshooting, scale-up, and simulation-driven engineering decisions.

Whether you need aerodynamic analysis, multiphase reactor modeling, heat-transfer investigation, or a customized multiphysics simulation, I bring together fluid mechanics, heat and mass transfer, chemical engineering, numerical methods, and engineering judgment to deliver results that are technically rigorous and practically useful.

I am open to collaborating on challenging CFD, multiphysics, and R&D projects where accurate physics and meaningful engineering insight matter.
