Abstract For the present study numerical simulations of subcooled flow boiling FC-72 in microgravity have been conducted to accompany experiments performed on International Space Station (ISS). The domain represents geometry experimental test cell. all open source framework OpenFOAM was employed, including extensions interFoam solver, which developed at authors’ institute. A reference case has ...

The numerical simulation and experimental validations of the growth and departure of a single bubble on a horizontal heated surface during pool boiling under reduced gravity conditions have been performed here. A finite difference scheme is used to solve the equations governing mass, momentum and energy in the vapor liquid phases. The vaporliquid interface is captured by level set method, which...

A strong correlation exists between subcooled boiling in assembly subchannels and CRUD deposition. In this work a genetic algorithm is used to optimize 17 x PWR fuel have minimized boiling, peak kinf, maximized end of cycle kinf. Optimization these parameters act as surrogate for the optimization deposition assemblies due their correlation. Subcooled measured by vapor void sub channel, values a...

The departure of nitrogen bubbles from duplex stainless steel (DSS) is essential for studying the precipitation behavior during solidification. In current work, numerical and theoretical derivation analytical formula were used to study bubble at solid–liquid interface. paper, radius was deduced by analysis. Based on works subcooled boiling flow, forces analyzed critical condition theoretically ...
