Osama A.

Top Rated Mechanical Engineer specializing in Computational Fluid Dynamics (CFD), HVAC simulation, and building airflow and thermal comfort analysis. I help clients analyze and optimize complex airflow, ventilation, temperature, and thermal comfort problems using CFD and engineering simulation tools. My focus is on HVAC and building applications, including indoor airflow analysis, ventilation performance, thermal comfort, and HVAC system optimization. CFD & Building Simulation • HVAC and indoor airflow CFD analysis using ANSYS Fluent • Air velocity, temperature, pressure, and airflow distribution • Ventilation and air distribution analysis • Thermal comfort assessment using PMV, PPD, and related comfort parameters • Relative humidity, operative temperature, draft risk, and indoor environmental analysis • HVAC supply/return airflow optimization • Identification of short-circuiting, dead zones, recirculation, and poor air distribution • Building and room-level CFD analysis for occupied spaces • Visualization and interpretation of CFD results for engineering decisions • Mesh generation using ANSYS Meshing and ANSYS Fluent Meshing HVAC Engineering • HVAC load calculations and equipment selection • Duct sizing and airflow calculations based on ASHRAE standards • Supply and return air distribution analysis • HVAC diffuser, grille, and register performance assessment • Ventilation and indoor air quality analysis • Thermal comfort evaluation and HVAC optimization CFD Applications I have experience applying CFD to: • Commercial and residential buildings • Offices and occupied spaces • Industrial facilities • Data centers and thermal management • Heat exchangers and fluid systems • Pumps, compressors, and other fluid-handling equipment Software ANSYS Fluent | ANSYS CFX | OpenFOAM | ANSYS Meshing | Fluent Meshing | ICEM CFD SpaceClaim | SolidWorks | Rhino | Revit My goal is not only to produce CFD contours, but to turn simulation results into clear engineering conclusions and practical design recommendations.
