L'activitat científica del grup està centrada en l'àmbit de les Enginyeries Mecànica i Aeroespacial amb l'objectiu d'estudiar el disseny i optimització d'equips i sistemes tèrmics i aerodinàmics, això com millorar la seva eficiència. Per a la realització d'aquests estudis, el grup utilitza tècniques de simulació numèrica avançada, incloent tècniques de supercomputació per a les quals el grup compta amb especialistes d'alt nivell, així com també fa servir tècniques experimentals.
