Flow separation control over NACA 0015 airfoil by swirling flow synthetic jet actuator
- CFD study of the model.
- Investigate boundary layer suction and boundary layer re-energizing.
- Use of LES WALE model instead of Smagorinsky Model. The WALE model is designed to return the correct wall asymptotic behavior for wall bounded flows. Another advantage of the WALE model is that it returns a zero turbulent viscosity for laminar shear flows. This allows the correct treatment of laminar zones in the domain. So, WALE model should yield better result.
- Compare results with previously documented work done by D. You and Parviz Moin (Link) and J. L. Gilarranz et. al. (Link) to verify the improvements.
For the ease of result comparison the computational domain is exactly same as computational domain proposed by D. You and Parviz Moin (Link).
Design optimization of autofrettaged metal-ceramic FGM and layered pressure vessel
- Instead of a user defined custom FGM material, 20 layers having different Al-Al2O3 percentage alloy will be used. However, more the number of layers the more accurate model of the material will be formed.
- The inner surface will be 100% Al and the outer most surface will be 100% Al2O3.
- Mechanical properties of Al2O3-Al FGM are obtained from the work of B.H. Jahromi et. al. (Link). However, thermal properties of the FGM are not investigated yet.
