Coanda jet lift enhancement : two-dimensional computational studies.


Djojodihardjo, Harijono and Abdul Hamid, Mohd Faisal (2012) Coanda jet lift enhancement : two-dimensional computational studies. In: 4th AUN/SEED-Net Reginal Conference on Mechanical and Aeronautical Engineering 2012, 10-11 Jan. 2012, Ho Chi Minh City, Vietnam. (pp. 1-10).

Abstract / Synopsis

The influence of Coanda effect for lift generation and enhancement, following renewed interest elsewhere, is investigated using CFD simulation. To that end, attention is focussed on twodimensional configuration and Coanda-Jet located at the trailing edge, to reveal the key elements that could exhibit the desired performance criteria for lift enhancement and drag reduction, or a combination of both. Parametric studies are carried out to obtain some optimum configuration, by varying pertinent airfoil geometrical and Coanda-Jet parameters. Particular attention is also given to turbulence modelling, by meticulous choice of appropriate turbulent models and scaling, commensurate with the grid generation, CFD code utilized and computational effectiveness. The present two-dimensional Coanda-Jet studies are carried out with wind turbine and micro-air-vehicle design in view.
