Flux-controlled wall model for large eddy simulation integrating the compressible law of the wall
Youjie Xu, Steffen J. Schmidt, Nikolaus A. Adams
Recent advances in velocity and temperature transformations have enabled recovery of the law of the wall in compressible wall-bounded turbulent flows. Building on this foundation,…
Temperature transformation recovering the compressible law of the wall for turbulent channel flow
Youjie Xu, Steffen J. Schmidt, Nikolaus A. Adams
Velocity and temperature distributions are both crucial for modeling compressible wall-bounded turbulent flows. The compressible law of the wall for velocity has been extensively e…
Rational-WENO: A lightweight, physically-consistent three-point weighted essentially non-oscillatory scheme
Shantanu Shahane, Sheide Chammas, Deniz A. Bezgin +8
Conventional WENO3 methods are known to be highly dissipative at lower resolutions, introducing significant errors in the pre-asymptotic regime. In this paper, we employ a rational…
Unitary Quantum Algorithm for the Lattice-Boltzmann Method
David Wawrzyniak, Josef Winter, Steffen Schmidt +4
We present a quantum algorithm for computational fluid dynamics based on the Lattice-Boltzmann method. Our approach involves a novel encoding strategy and a modified collision oper…
An efficient and robust all-Mach consistent numerical scheme for simulation of compressible multi-component fluids including surface tension, cavitation, turbulence modeling and interface sharpening on compact stencils
Yu Jiao, Steffen J. Schmidt, Nikolaus A. Adams
We present an efficient, fully conservative numerical scheme valid in the entire range of highly to weakly compressible flows using a single-fluid four equation approach together w…
Numerical prediction of erosion due to a cavitating jet
Theresa Trummler, Steffen J. Schmidt, Nikolaus A. Adams
We numerically investigate the erosion potential of a cavitating liquid jet by means of high-resolution finite volume simulations. As thermodynamic model, we employ a barotropic eq…
Numerical investigation of non-condensable gas effect on vapor bubble collapse
Theresa Trummler, Steffen J. Schmidt, Nikolaus A. Adams
We numerically investigate the effect of non-condensable gas inside a vapor bubble on bubble dynamics, collapse pressure and pressure impact of spherical and aspherical bubble coll…
Effect of stand-off distance and spatial resolution on the pressure impact of near-wall vapor bubble collapses
Theresa Trummler, Steffen J. Schmidt, Nikolaus A. Adams
We consider the collapse behavior of cavitation bubbles near walls under high ambient pressure conditions. Generic configurations with different stand-off distances are investigate…
Large eddy simulations of cavitating flow in a step nozzle with injection into gas
Theresa Trummler, Daniel Rahn, Steffen J. Schmidt +1
We present results of large eddy simulations of a cavitating nozzle flow and injection into gas, investigating the interactions of cavitation in the nozzle, primary jet breakup, ma…
Investigation of condensation shocks and re-entrant jet dynamics in a cavitating nozzle flow by Large-Eddy Simulation
Theresa Trummler, Steffen J. Schmidt, Nikolaus A. Adams
Cloud cavitation is related to an intrinsic instability where clouds are shed periodically. The shedding process is initiated either by the motion of a liquid re-entrant jet or a c…
Near-surface dynamics of a gas bubble collapsing above a crevice
Theresa Trummler, Spencer H. Bryngelson, Kevin Schmidmayer +3
The impact of a collapsing gas bubble above rigid, notched walls is considered. Such surface crevices and imperfections often function as bubble nucleation sites, and thus have a d…
Implicit Large Eddy Simulation of Cavitation in Micro Channel Flows
S Hickel, M. Mihatsch, S. J. Schmidt
We present a numerical method for Large Eddy Simulations (LES) of compressible two-phase flows. The method is validated for the flow in a micro channel with a step-like restriction…
