Entrainment in Refrigerated Air Curtains [PDF]

, 2002
Refrigerated air curtains are used in supermarket display cases to keep warm ambient air from entering the refrigerator case. Entrainment of ambient air into the curtain by shear layer mixing contributes to both the sensible and the latent heat load on ...

Microstructure measurements and estimates of entrainment in the Denmark Strait overflow plume [PDF]

, 2013
To examine processes controlling the entrainment of ambient water into the Denmark Strait overflow (DSO) plume/gravity current, measurements of turbulent dissipation rate were carried out by a quasi-free-falling (tethered) microstructure profiler (MSP ...

Potential contribution of biomass gasification‐based technology in energy transition: a technical review coupled with bibliometric studies

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Biomass gasification technology has been extensively researched around the world; however, there is a need to evaluate the current research landscape and evolutionary direction of research in the broader context of energy transition. A systematic bibliometric analysis of the Web of Science database was performed for articles that fall within ...

Numerical Visualization of Plunging Water Jet using Volume of Fluid Model

Journal of Applied Fluid Mechanics, 2018
A plunging liquid jet is defined as a moving column of liquid passing through a gaseous headspace, air in our case, before impinging a free surface of receiving liquid pool. The mechanism of air entrainment due to plunging liquid jets is very complex and

Scaffolding a Low‐Cost Experiential Bioreactor Module: Reducing Cognitive Load to Enhance Competency and Self‐Efficacy

Biochemistry and Molecular Biology Education, EarlyView.
ABSTRACT Low‐cost experiential modules are critical for democratizing biotechnology education, yet most undergraduates lack hands‐on experience with continuous‐culture bioreactor operations, which are fundamental to industrial bioprocessing. This study employed design‐based research across two iterative cycles (Fall 2024, n = 8; Fall 2025, n = 11) to ...
