Vortical Structures on Three-Dimensional Shock Control Bumps

Toward Numerical Optimization of Buffet Alleviating Three-Dimensional Shock Control Bumps

Besides its original purpose of reducing wave drag at transonic speed it has been shown that shock control bumps (SCB) can additionally be used for buffet alleviation. Considering 3-D-SCBs as a novel sort of vortex generators these bumps introduce, when carefully designed, streamwise vorticity into the flow and thereby prevent the boundary layer (BL) from early separation. The current paper pre...

Vortical control of forced two-dimensional turbulence

A new numerical technique for the simulation of forced two-dimensional turbulence [D. Dritschel and J. Fontane, “The combined Lagrangian advection method,” J. Comput. Phys. 229, 5408–5417 (2010)] is used to examine the validity of KraichnanBatchelor scaling laws at higher Reynolds number than previously accessible with classical pseudo-spectral methods, making use of large simulation ensembles ...

Three Dimensional Thermal Shock Problem in Magneto-Thermoelastic Orthotropic Medium

The paper is concerned with the study of magneto-thermoelastic interactions in three dimensional thermoelastic medium under the purview of three-phase-lag model of generalized thermoelasticity. The medium under consideration is assumed to be homogeneous orthotropic medium. The fundamental equations of the three-dimensional problem of generalized thermoelasticity are obtained as a vector-matrix ...
