A unique concept of utilizing localized surface compliance is proposed to suppress deep cavity aeroacoustics at a low Mach number. The core idea provide local absorption the energy aeroacoustic processes supporting flow self-sustained feedback loop responsible for tonal noise generation. studied with past length-to-depth ratio 0.4 freestream number 0.09 and Reynolds based on length 4 × 104 usin...

The Lattice Boltzmann Method (LBM) has numerous computational advantages, such as the simplicity of programming, the ability to incorporate microscopic interactions, and the easy parallelization of algorithms. The traditional lattice Boltzmann model has a constraint of small mach number(the velocity of fluid must be less than 0.3 mach). This paper presents a novel lattice Boltzmann method to si...

Abstract In a collisionless shock the energy of directed flow is converted to heating and acceleration charged particles, magnetic compression. low-Mach number shocks downstream ion distribution made directly transmitted ions. higher-Mach reflection important. With increase Mach number, rippling develops, which expected affect dynamics. Using tracing in model front, distributions ions are analy...
