CHT simulations

Thermal failures are among the most costly and preventable engineering problems. Our CFD consulting team runs conjugate heat transfer simulations that couple fluid flow and solid conduction in a single domain, giving you a complete picture of how heat moves through your system. Trusted by aerospace, automotive, and energy clients to validate designs against temperature limits before any prototype is built.

• Conjugate heat transfer (CHT) simulation
• Forced and natural convection analysis
• Electronics and PCB thermal management simulation
• Heat exchanger and cold plate design validation
• Radiation heat transfer modeling (surface-to-surface, DO model)
• Thermal stress coupling with structural analysis

Eulerian, Lagrangian and VOF

Multiphase flow problems require specialized modeling that goes beyond standard single-phase CFD. As one of the leading CFD simulation companies in this domain, AES has deep expertise in Eulerian-Eulerian, Eulerian-Lagrangian, and VOF methods for gas-liquid, liquid-liquid, and particle-laden flows across oil and gas, spray, and reactor applications.

• Eulerian multiphase and mixture model simulations
• Multi-component and multi-phase flow modeling
• Lagrangian particle tracking (DPM) and spray modeling
• Erosion and deposition prediction
• Bubble column and fluidized bed reactor simulation
• Liquid-liquid extraction and separation modeling

MRF and sliding mesh

Rotating machinery operates under demanding fluid-dynamic conditions where small inefficiencies translate directly into energy loss and downtime. Our CFD consulting services for turbomachinery cover pumps, compressors, turbines, fans, and blowers using MRF, sliding mesh, and rotor-stator interaction models to resolve blade loading, pressure rise, and efficiency maps across the full operating range.

• Axial and centrifugal pump, compressor, and turbine CFD
• Blower and cooling fan performance mapping
• Swirling and rotating flow analysis (MRF, sliding mesh)
• Cavitation onset and bubble dynamics prediction
• Lateral and torsional rotor vibration analysis
• Root cause investigation for machinery failures

DOE, adjoint and surrogate workflows

This is the most advanced layer of our CFD analysis services. We integrate parametric CFD studies with design of experiments (DOE) and adjoint-based shape optimization to systematically improve product performance. Engineering teams that work with our CFD consulting team reach the optimal design faster because we pair simulation expertise with engineering judgment to prioritize the variables that deliver the most impact.

• Parametric CFD sweep studies (geometry and operating conditions)
• Adjoint-based shape optimization
• HVAC airflow and energy efficiency optimization
• Underhood and powertrain thermal management optimization
• Heat exchanger and cold plate geometry optimization
• Design of Experiments (DOE) and surrogate model CFD workflows
