A 20° SAE Notchback model was utilised in a comparative study between RANS methods with both unstructured and structured grids and Implicit DES methods with structured grids. Experimental data acquired in the Loughborough University wind-tunnel with this Notchback geometry was utilised in this investigation to gauge the accuracy of the two methods. The pressure coefficient at 5 elevations on the base surface of the model was monitored, with the Implicit DES method yielding the lowest mean error of 2.7% against the 13% resulting from RANS.
