Gravity independent subcooled flow boiling heat transfer regime
Experimental Thermal and Fluid Science, 2004 Abstract Using an existing model for vapor bubble detachment, a subcooled flow boiling regime was identified where vapor bubble dynamics are independent of the gravitational field. The Jakob number and a dimensionless flow parameter were used to identify the boundaries of this regime.

A Methodology to Integrate Closed‐Cycle Heat Pumps into Batch Distillation Columns
Chemie Ingenieur Technik, EarlyView.Batch distillation often cannot use vapor recompression due to contamination risks in food and pharma. This study proposes a design for integrating closed‐loop heat pumps using natural fluids. Results show significant energy savings, offering a sustainable alternative to traditional setups.
