MIRA's fluids engineering team provides state-of-the-art capabilities for the aerodynamic development of modern high-speed trains.
MIRA’s aerodynamics team uses state-of-the-art CFD simulation techniques to optimise exterior locomotive design and inter-car spacing in order to reduce aerodynamic drag and deliver substantial energy and fuel savings.
CFD simulation is also extensively employed to improve train side-stability by investigating cross-wind behaviour when the train is subjected to strong wind gusts or passing other vehicles. Development here is mainly focused at improving vehicle stability by reducing tipping moment.
Following initial development, validation can take place at model-scale in MIRA's aerodynamic wind tunnel - the largest in the UK. No other UK consultancy can offer the range of tools that MIRA has, or the depth of experience and industry knowledge that exists in its aerodynamics engineering team.
MIRA has been involved in several research projects for the study of the unsteady pressure field due to the slipstreams and the tail wake of high speed trains by means of experimental investigations at reduced scale and CFD modelling of the coupled system. This unsteady pressure field can sometime generate unsteady forces and moments including dynamic excitation coupled with the aerodynamic forces generated by the train.
Validation of the CFD model can take place using scale models in the UK's largest wind tunnel .
MIRA’s aerodynamics team use state of the art Computational Fluid Dynamics (CFD) simulation techniques to deliver substantial aerodynamic drag savings.
Validation can take place in the UK's only full scale automotive wind tunnel.
MIRA has the UK’s only full scale aerodynamic wind tunnel providing a cost-effective solution for aerodynamic test and development for a wide range of applications from automotive vehicle development, motorsport, aerospace, wind engineering, structures and sport sectors to name but a few.
