Aerospace CFD Consulting - Computational Fluid Dynamics
External Supersonic Flows:
CFD analysis of external supersonic flows is crucial for understanding the behavior of planes, bluff bodies, airfoils etc. JLR personnel have extensively studied drag and lift on bodies, shapes of shock waves, stresses on bodies due to shock etc in very high speed compressible flows. This work is highly useful in minimizing prototyping and wind tunnel studies. A significant use is in optimization studies where parameters like multiple angles of attack or varying velocities can be studied easily and for significantly less cost and time.
Internal Supersonic Flows:
CFD analysis of internal parts like nozzles and compressors which achieve high speed are among the most sophisticated industrial applications of CFD. JLR application engineers have extensively studied problems of oblique intersecting shock waves, ultra high pressure flows (~20 Gpa), multi-gas and multiphase flows inside high Mach number nozzles, and ultra high compression flow of gases inside machinery. These studies have resulted in fundamental understanding of the internal operations of machinery where internal experimental studies are impossible. In addition, we have also assisted with optimization studies, studies of multiple configurations and flow conditions, and geometry changes with significantly less cost and effort compared to prototyping.
Transonic/Subsonic Flows:
JLR engineers have performed numerous analyses of subsonic and transonic flows in both external and internal regimes using CFX and Fluent. We have analyzed drag and lift of aerodynamic bodies in 2D and 3D; efficiency of nozzles, compressors, and turbines; angle of attack studies; and engine design. In addition, we have the ability to study reacting and combusting flows inside propulsion devices using Fluent to analyze fuel efficiency and exhaust studies.
Aerospace HVAC:
We have utilized CFD tools to analyze the interior performance of cabins in planes. In addition, CFD is also useful for analyzing on-board refrigeration of food storage, studying effects of air pressure changes on cabin comfort levels, effects of external turbulence on internal cabin conditions etc. We have performed optimization studies crucial to interior design of new planes.
JLR’s familiarity with Fluent and CFX, as well as our knowledge of specialized supersonic and aerodynamic solvers make us ideal choices for studying aerospace problems.
We have a new 100+ node Cluster for large scale CFD and FEA parallel processing simulations using ANSYS CFX and ANSYS FLUENT. This uses the latest in low-power dual- quad-core technology for extremely low power, high performance chips. If you have a large model you need to solve, contact us about our services for helping you solve your large or long runtime transient models!
We have offices located across North America. Satellite offices are located in Rochester, New York; Toronto, Canada; Montreal, Canada; Atlanta, Georgia; and Cleveland, Ohio.
