Modeling of pressure drop and heat transfer for flow boiling in a mini/micro-channel of rectangular cross-section [PDF]
arXiv, 2019 In the present study, a 1-dimensional model is proposed to estimate the pressure drop and heat transfer coefficient for flow boiling in a rectangular microchannel. The present work takes into account the pressure fluctuations caused due to the confined bubble growth and the effect of pressure fluctuations on the heat transfer characteristics.

Determination of one unknown thermal coefficient through a mushy zone model with a convective overspecified boundary condition [PDF]
arXiv, 2015 A semi-infinite material under a solidification process with the Solomon-Wilson- Alexiades's mushy zone model with a heat flux condition at the fixed boundary is considered. The associated free boundary problem is overspecified through a convective boundary condition with the aim of the simultaneous determination of the temperature, the two free ...

Improvement of heat exchanger efficiency by using hydraulic and thermal entrance regions [PDF]
arXiv, 2018 This study investigates one of the possible approaches of improvement of heat exchangers efficiency. Literature review shows that most approaches of improvement are based on the heat transfer surface increasing and laminar-to-turbulent flow transition using different types of riffles forming and shaped inserts.
