Numerical modelling of conjugate heat transfer in force convective flow environment using a combined boiling model (CBM)

Results in Engineering
Subcooled flow boiling is a crucial heat transfer mechanism in which the fluid temperature exceeds its saturation point, leading to phase change. Computational Fluid Dynamics (CFD) is a powerful tool for investigating such phenomena.
