UNCERTAINTY IN COMPUTATIONAL FLUID-DYNAMICS

The Annual EPSRC/IMechE Expert Meeting brought together some 44 expert s to consider sources of uncertainty in computational fluid dynamics ( CFD). Presentations and discussions covered modelling, numerical solut ion techniques, boundary conditions, evaluation protocols and QA (qual ity assurance) procedures. The principal conclusions to emerge were: ( a) the need for additional collaborative validation studies; (b) the d esirability of introducing appropriate QA procedures, possibly based o n the CFD Community Club initiative; (c) the need for additional postg raduate training, possibly based on the IGDS principle; (d) the value of continuing work in modelling and error estimation techniques for nu merical schemes.
