Numerical simulation study of optimal inlet conditions of rectifier nozzle type distributor

Shipin yu jixie, 2022
Objective: In order to effectively improve or eliminate as much as possible in the refrigeration system, the uneven distribution of gas-liquid two-phase refrigerant in the evaporator leads to the performance decline of the refrigeration system.

Hydrodynamic and mass transfer in inertial gas–liquid flow regimes through straight and meandering millimetric square channels [PDF]

, 2011
Heat-exchanger reactors are an important part of process intensification technology. For plate geometries, one solution for intensifying transfer and increasing residence times is to construct two-dimensional meandering channels.

Mathematical model for flow regime transition conditions of gas-liquid two-phase flow in natural gas reservoir fracture

Meitan kexue jishu
The flow of gas-liquid two-phase flow in reservoir fractures may exhibit various flow regimes, such as bubble flow, slug flow, and annular mist flow. Identifying the conditions for the transition between these flow regime is essential for understanding ...

Modelling of transient gas-liquid flow and pigging in pipes [PDF]

, 1999
More and more transient gas-liquid operations in pipes are being successfully applied in the oil and gas industry. Pigging in two-phase pipelines, to remove liquid accumulation or for cleaning purposes, is an important transient operation.

Systemic dysregulation of apolipoproteins in amyotrophic lateral sclerosis serum

FEBS Open Bio, EarlyView.
Amyotrophic lateral sclerosis (ALS) is a fatal disease that damages motor neurons. This study found that people with ALS show significant changes in blood fats and the proteins that carry them. Several apolipoproteins were higher, lipid balances were altered, and normal protein–lipid relationships were disrupted.
