How to Recover Oscillation-Free Pressure in Real Fluids: The RFQC Method and Its Liquid-Upwind Anomaly
Haotong Bai, Bai Haotong, Yixin Yang +7
From the perspective of continuum thermodynamics, we revisit the pressure oscillation problem in finite-volume methods for multiphase real fluids and clarify the physical counterpa…
Analysis and Numerics of a Stationary Drift-Diffusion Model for Electrical Discharge in MEMS
Runan He, Wenjia Xie
This work presents the analysis and numerical simulation of a stationary drift-diffusion model for electrical discharge in micro-electro-mechanical systems (MEMS). The model couple…
An Oscillation-Free Real Fluid Quasi-Conservative Finite Volume Method for Transcritical and Phase-Change Flows
Haotong Bai, Wenjia Xie, Yixin Yang +2
A new Real Fluid Quasi-Conservative (RFQC) finite volume method is developed to address the numerical simulation of real fluids involving shock waves in transcritical and phase-cha…
Flash evaporation Riemann Problem: Formulation and its Exact Solution
Haotong Bai, Ping Yi, Yixin Yang +3
Flash evaporation, a liquid-to-gas phase transition phenomenon in real fluids, is prevalent in aerospace propulsion systems. To elucidate the physical mechanisms of such complex fl…
