A New Method to Experimentally Investigate Local Pressure Loss of Oil-Water Two-Phase Flow through Pore Throats [PDF]

E3S Web of Conferences, 2020
To investigate the resistance performance of pore throats in porous media, a new method was used to conduct experiments to indirectly measure the local pressure loss of single-phase water and oil- water two-phase flow through pore-throat structures. Four

Influence of a Periodical Fluctuation on a Profile Loss of a Cascade : Part I, Determination of the Total Pressure Loss Coefficient

Bulletin of JSME, 1984
Experiments on the total pressure loss coefficient of a cascade in a periodically fluctuating flow generated with a rotating cylinder row are described. similarity of a flow field obtained and one developing after an actual compressor rotor is examined, and the total pressure loss of a test cascade is determined from the measurement of wake profiles ...

Optimization strategies for the design of pre-cooler based on the synergistic air-breathing rocket engine

Case Studies in Thermal Engineering
A foundation for the engineering of pre-coolers is provided to understand the flow and heat transfer characteristics of air pre-coolers. Using the pre-cooler in the combustor of the Synergistic Air-Breathing Rocket Engine (SABRE) as the research object ...

Effect of Cascade Surface Roughness on Boundary Layer Flow Under Variable Conditions

Frontiers in Energy Research, 2022
Under the influence of many factors, the surface roughness of the cascade will change during turbomachinery operation, which will affect the boundary layer flow of the cascade.

CFD verification of total pressure loss coefficient for gas-liquid two-phase flow

Journal of Physics: Conference Series
Abstract Traditionally, we design gas-liquid two-phase flow systems with pressure loss that is assumed by homogeneous flow. However, in real phenomena, the flow rate of water or air through a system cannot be correctly predicted unless we evaluate by the total pressure loss.

Correlation between total pressure losses of highly loaded annular diffusers and integral stage design parameters

Journal of the Global Power and Propulsion Society, 2018
Diffusers convert kinetic flow energy into a rise in static pressure. This pressure recovery is the primary aerodynamic design objective for exhaust gas diffusers in power-generating steam and gas turbines. The total pressure loss is an equally important

Optimization design of dual microjets for the shock wave/boundary layer interaction control in the supersonic flow

AIP Advances, 2023
The shock wave/boundary layer interaction phenomenon is harmful to the performance improvement of the hypersonic vehicle, and the microjet flow control scheme was introduced to minimize the total volume of the separation bubble and maximize the total ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

FEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...
