Review of computational studies on boiling and condensation

Behaviour of Condensation for High Steam Energy and Water in Vertical Annular Channel

“…Numerical method or computational approaches currently become famous nowadays to analyse phase change phenomena [5]. Many researcher studies the condensation in high speed velocity as steam plume condensation [6][7][8][9].…”

Modeling of Pressure Drop During Refrigerant Condensation in Pipe Minichannels

“…The analysis of global trends in the development of distributed energy indicates an increasing demand for miniaturized devices carrying large heat flux. There is a need for miniaturization in many industries, including electronics, aerospace, telecommunications, medicine, microbiology, etc [11]. Ongoing work related to the improvement of existing devices and the development of new ones is underway in the power sector, as well as for refrigeration and air conditioning applications.…”

Modeling of bubbles hydrodynamics and mass transfer in electrochemical gas-evolving systems

“…The geometry of the interface is initialized at the There are two main categories of VOF techniques: those in which the interface is captured by reconstructing the interface using mathematical fittings and others in which an algebraic approach is used to capture the interface. VOF methods that involve interface reconstruction to determine the interface shape use piecewise constant or piecewise linear schemes [189]. In these methods the interface is captured with zero thickness by implementing either simple line interface calculation (SLIC) [190], which is a piecewise constant scheme, or piecewise linear interface calculation (PLIC) [191], a piecewise linear scheme.…”

“…For example, the density, ρ, and viscosity, µ, of the one-fluid system are evaluated as follows [189]:…”

“…As time evolves ψ cannot maintain the signed distance property resulting in error in capturing the interface curvature and, therefore, numerical dissipation takes place resulting mass conservation issues [189]. For example, in cases where the interface is stretched, the gradient of ψ becomes steeper, and when the interface is compressed the gradient becomes smaller [174].…”
