CFD Simulation Services in Saudi Arabia

Computational fluid dynamics simulation for flow optimisation, heat transfer, HVAC, and process equipment analysis across oil & gas and industrial projects in KSA.

SLETEC Engineering delivers computational fluid dynamics (CFD) simulation services for engineering projects across Saudi Arabia. Using ANSYS Fluent and CFX, our CFD engineers model fluid flow, heat transfer, and mass transport phenomena to predict equipment performance, identify design risks, and support optimisation decisions before physical construction or procurement. CFD is a cost-effective tool for validating process designs and avoiding expensive rework.

Our CFD capabilities cover a broad range of industrial applications: single-phase and multiphase flow in process vessels and piping, shell-and-tube and air-cooled heat exchanger thermal performance, HVAC room airflow and ventilation effectiveness, pressure drop prediction in complex piping geometries, flow-induced vibration risk screening, and gas dispersion modelling for safety studies. Each simulation is set up with engineering-grade mesh quality, validated turbulence models, and boundary conditions derived from actual process data.

Results from SLETEC CFD studies are delivered in a structured technical report format, including geometry description, mesh quality metrics, solver setup, convergence assessment, and detailed visualisation of flow fields, temperature distributions, and pressure maps. Our reports are written to support engineering decision-making and are suitable for client submission and third-party technical review.

Engineering documentation prepared with reference to API, ASME, AISC, AWS, ISO, Saudi Aramco, SABIC and client project specifications where applicable.

Frequently Asked Questions

What CFD simulation services does SLETEC provide in Saudi Arabia?

SLETEC provides CFD simulation for single-phase and multiphase flow analysis, heat exchanger thermal performance studies, HVAC room airflow and ventilation analysis, pressure drop calculations in piping networks, combustion and furnace modelling, and dispersion analysis for gas release scenarios in oil & gas and industrial facilities.

What CFD software does SLETEC use for simulation in KSA?

SLETEC primarily uses ANSYS Fluent and ANSYS CFX for industrial CFD simulations. For HVAC and building airflow studies, we also use SolidWorks Flow Simulation. All simulations are validated against applicable analytical methods and published benchmark data where available.

Can CFD simulation help optimise heat exchanger designs?

Yes. CFD simulation is a powerful tool for evaluating heat exchanger thermal performance, identifying flow maldistribution, studying fouling-prone zones, and comparing design variants. SLETEC uses CFD to supplement analytical calculations and validate shell-and-tube and plate heat exchanger designs.

How are CFD results reported by SLETEC?

SLETEC delivers a comprehensive CFD report including geometry description, mesh quality summary, boundary conditions, solver settings, convergence history, flow visualisation plots (velocity, pressure, temperature contours, streamlines), and a quantitative summary of key results with engineering interpretation.
