Domain-Adapted Deep Optical Flow for Multiphase Velocimetry in Unsteady Cloud Cavitation
Naga Nitish Chamala, Sanjay Vasanth Kethanur Balasubramaniam, Olivier Coutier-Delgosha
Time-resolved velocimetry inside cloud cavitation remains a fundamental measurement problem. Particle image velocimetry (PIV) requires uniform tracer seeding and undistorted partic…
A novel data-driven method for augmenting turbulence modeling for unsteady cavitating flows
Dhruv Apte, Nassim Razaaly, Yuan Fang +3
Cavitation is a highly turbulent, multi-phase flow phenomenon that manifests in the form of vapor cavities as a result of a sudden drop in the liquid pressure. The phenomenon has b…
Investigation of cloud cavitating flow in a venturi using Adaptive Mesh Refinement (AMR)
Dhruv Apte, Mingming Ge, Olivier Coutier-Delgosha
Unsteady cloud cavitating flow is detrimental to the efficiency of hydraulic machinery like pumps and propellers due to the resulting side-effects of vibration, noise and erosion d…
Bubble collapse near a wall. Part 1: An experimental study on the impact of shock waves and microjet on the wall pressure
Roshan Kumar Subramanian, Zhidian Yang, Francesco Romanò +1
This study examines the pressure exerted by a cavitation bubble collapsing near a rigid wall. A laser-generated bubble in a water basin undergoes growth, collapse, second growth, a…
Numerical investigation of three-dimensional effects of cavitating flow in a venturi-type hydrodynamic cavitation reactor
Dhruv Apte, Mingming Ge, Olivier Coutier-Delgosha
The concept of Hydrodynamic Cavitation (HC) has emerged as a promising method for wastewater treatment, bio-diesel production and multiple other environmental processes with Ventur…
A comparative evaluation of turbulence models for simulation of unsteady cavitating flows
Dhruv Apte, Mingming Ge, Olivier Coutier-Delgosha
Cavitation is a complex multiphase phenomenon characterised by vapour bubbles forming due to a sudden pressure drop and is often accompanied by increased hull vibrations, increased…
Analysis of high-energy drop impact onto deep liquid pool
Hui Wang, Shuo Liu, Annie-Claude Bayeul-Lainé +3
The present work is devoted to the analysis of drop impact onto a deep liquid pool. It is focused on the effects of high-energy splash regimes, caused by the impact of large raindr…
Wave Statistics and Energy Dissipation of Breaking Waves Generated by a Wave Plate
Shuo Liu, Hui Wang, Annie-Claude Bayeul-Lainé +3
The present study focuses on direct numerical simulations of breaking waves generated by a wave plate at constant water depths. The aim is to quantify the dynamics and kinematics i…
Evaluation of ensemble methods for quantifying uncertainties in steady-state CFD applications with small ensemble sizes
Xinlei Zhang, Heng Xiao, Thomas Gomez +1
Bayesian uncertainty quantification (UQ) is of interest to industry and academia as it provides a framework for quantifying and reducing the uncertainty in computational models by…
Enforcing Boundary Conditions on Physical Fields in Bayesian Inversion
Carlos A. Michelén Ströfer, Xinlei Zhang, Heng Xiao +1
Inverse problems in computational mechanics consist of inferring physical fields that are latent in the model describing some observable fields. For instance, an inverse problem of…
Study of the cavitating instability on a grooved Venturi profile
Amélie Danlos, Jean-Elie Mehal, Florent Ravelet +2
Cavitation is a limiting phenomenon in many domains of fluid mechanics. Instabilities of a partial cavity developed on an hydrofoil, a converging-diverging step or in an inter-blad…
