Numerical Experimentations in the Dynamics of Particle-Laden Supersonic Impinging Jet Flow

SESSION: Doctoral Showcase - Early Research Showcase

EVENT TYPE: Doctoral Showcase

TIME: 3:30PM - 5:00PM

SESSION CHAIR: Wojtek James Goscinski

Presenter(s):Paul C. Stegeman


The proposed thesis will be a numerical investigation of the physical mechanisms of under-expanded supersonic impinging (USI) jet flow and particle transport within it. A numerical solver has been developed implementing the LES methodology on a cylindrical curvilinear grid using both compact and explicit finite differencing. A hybrid methodology is used to accurately resolve discontinuities in which a shock selection function determines if the solver should apply a shock-capturing algorithm or a differcing algorithm. Particle transport within the USI jet will be studied by modeling the individual particles in a Lagrangian phase. Biased interpolation schemes with similar properties to the shock-capturing schemes are being developed. The use of these shock-optimized interpolation schemes will also be dependent on the shock-selection function that is used in the fluid phase. This aims to improve the accuracy of the particles' dynamics as they travel through shock waves.
