Impact of alignments between fluctuating and mean density gradients on the scale-dependent energetics of stably stratified turbulence
Soumak Bhattacharjee, Stephen M. de Bruyn Kops, Andrew D. Bragg
Non-trivial alignments between vorticity and the strain-rate tensor play an important role in the evolution of velocity gradients and the energy cascade in isotropic turbulence. He…
Evolution of passive scalar mixing layers in stratified and unstratified homogeneous turbulence
Stephen M. de Bruyn Kops, Peter N. Blossey, James J. Riley
High-resolution large-eddy simulations of decaying stratified and unstratified homogeneous turbulence are used to understand the mixing of passive scalars in stably stratified flow…
Tensor network compression using fluid dynamics as a testbed: Analytical foundations in one dimension
Matthew D. Horner, Callum W. Duncan, Oliver T. Brown +2
High performance computers produce extreme-scale data sets that require sampling or compression if they are to be used to their full potential. Existing data compression techniques…
Equation-informed data-driven identification of flow budgets and dynamics
Nataliya Sevryugina, Serena Costanzo, Stephen de Bruyn Kops +3
Computational Fluid Dynamics (CFD) is an indispensable method of fluid modelling in engineering applications, reducing the need for physical prototypes and testing for tasks such a…
