  1. 1. Design of compact automotive heat exchanger, analysing the effects of RANS models and utilising Additive Manufacturing

    University essay from KTH/Fysik

    Author : Nikhil Srikkanth; Bartosz Brzuchalski; [2022]
    Keywords : Turbulence; Reynolds Averaged Navier-Stokes; KTH Formula Student; metal additive manufacturing; CFD; turbulent kinetic energy; boundary layer;

    Abstract : The analytical modelling of complex turbulent airflow remains one of the great unsolved mysteries of physics, but in this paper two widely used Reynolds Averaged Navier-Stokes models (k-$\epsilon$ and k-$\omega$ SST) are compared while designing a heat exchanger for the KTH Formula Student electric race car. CAD software was used to design lattices for the heat exchanger core and theorise about how to increase heat transfer while also taking into account the utilisation of metal additive manufacturing.
