Self-similar structure of non-isothermal variable-density mushy Stefan problems and an improved low-Mach enthalpy method
Yavkreet Swami, Amneet Pal Singh Bhalla
The enthalpy method was introduced in the late 1970s to simulate phase-change problems on fixed grids without explicitly tracking the moving phase-change front. It remains one of t…
Fixed-grid sharp-interface numerical solutions to the three-phase spherical Stefan problem
Yavkreet Swami, Jacob Barajas, Amneet Pal Singh Bhalla
Many metal manufacturing processes involve phase change phenomena, which include melting, boiling, and vaporization. These phenomena often occur concurrently. A prototypical 1D mod…
Simulating acoustically-actuated flows in complex microchannels using the volume penalization technique
Khemraj Gautam Kshetri, Amneet Pal Singh Bhalla, Nitesh Nama
We present a volume penalization technique for simulating acoustically-actuated flows in geometrically complex microchannels. Using a perturbation approach, the nonlinear response…
Analytical and numerical solutions to the three-phase Stefan problem with simultaneous occurrences of melting, solidification, boiling, and condensation phenomena
Mehran Soleimani, Kimmo Koponen, Nils Tilton +1
The one-dimensional (1D) Stefan problem is a prototypical heat and mass transfer problem that analyzes the temperature distribution in a material undergoing phase change. In additi…
Consistent continuum equations and numerical benchmarks for a perturbation-based, variable-coefficient acoustofluidic solver
Khemraj Gautam Kshetri, Amneet Pal Singh Bhalla, Nitesh Nama
We present a consistent continuum framework and a variable-coefficient acoustofluidic solver to analyze acoustic streaming. A perturbation approach is used to split the compressibl…
A consistent, volume preserving, and adaptive mesh refinement-based framework for modeling non-isothermal gas-liquid-solid flows with phase change
Ramakrishnan Thirumalaisamy, Amneet Pal Singh Bhalla
This work expands on our recently introduced low Mach enthalpy method [1] for simulating the melting and solidification of a phase change material (PCM) alongside (or without) an a…
