Mach number and wall thermal boundary condition effects on near-wall compressible turbulence
Akanksha Baranwal, Diego A. Donzis, Rodney D. W. Bowersox
We investigate the effects of thermal boundary conditions and Mach number on turbulence close to walls. In particular, we study the near-wall asymptotic behavior for adiabatic and…
Emergence of universal scaling in isotropic turbulence
Sualeh Khurshid, Diego Donzis, Katepalli R. Sreenivasan
Universal properties of turbulence have been associated traditionally with very high Reynolds numbers, but recent work has shown that the onset of the power-laws in derivative stat…
Evaluation of finite difference based asynchronous partial differential equations solver for reacting flows
Komal Kumari, Emmet Cleary, Swapnil Desai +3
Next-generation exascale machines with extreme levels of parallelism will provide massive computing resources for large scale numerical simulations of complex physical systems at u…
Laws of turbulence decay from direct numerical simulations
John Panickacheril John, Diego A Donzis, Katepalli R Sreenivasan
Inspection of available data on the decay exponent for the kinetic energy of homogeneous and isotropic turbulence (HIT) shows that it varies by as much as 100\%. Measurements and s…
Direct Numerical Simulations of turbulent flows using high-order Asynchrony-Tolerant schemes: accuracy and performance
Komal Kumari, Diego A. Donzis
Direct numerical simulations (DNS) are an indispensable tool for understanding the fundamental physics of turbulent flows. Because of their steep increase in computational cost wit…
A unified framework to generate optimized compact finite difference schemes
Vedang M. Deshpande, Raktim Bhattacharya, Diego A. Donzis
A unified framework to derive optimized compact schemes for a uniform grid is presented. The optimal scheme coefficients are determined analytically by solving an optimization prob…
