General relationships of dimensionless parameters for thermocapillary-buoyancy flow in side-heated annular pools

open access: yesCase Studies in Thermal Engineering, 2023
It is well-known that thermocapillary-buoyancy flow instability can be affected by several dimensionless control parameters. The general relationships among them are helpful for actively controlling flow instability but were not clear. This work reported

The Effect of Flow-Induced Vibration on Heat and Mass Transfer Performance of Hollow Fiber Membranes in the Humidification/Dehumidification Process

open access: yesMembranes, 2021
Cross-flow hollow fiber membranes are commonly applied in humidification/dehumidification. Hollow fiber membranes vibrate and deform under the impinging force of incoming air and the gravity of liquid in the inner tube.

Measurement and Prediction of Discharge Coefficients in Highly Compressible Pulsating Flows to Improve EGR Flow Estimation and Modeling of Engine Flows

open access: yesFrontiers in Mechanical Engineering, 2019
An assumption of constant discharge coefficient (Cd) is often made when modeling highly compressible pulsating engine flows through valves or other restrictions.

Pulsating strings with mixed three-form flux [PDF]

open access: yes, 2018
Circular strings pulsating in $AdS_3 \times S^3 \times T^4$ with mixed R-R and NS-NS three-form fluxes can be described by an integrable deformation of the one-dimensional Neumann-Rosochatius mechanical model.

Unsteady behaviours of a volute in turbocharger turbine under pulsating conditions

open access: yesJournal of the Global Power and Propulsion Society, 2017
Turbochargers are currently in their prime utilization period, which pushes for performance enhancement from conventional turbochargers and more often than not revisiting its design methodology.

Large Eddy Simulation of combustion instabilities in a lean partially premixed swirled flame [PDF]

open access: yes, 2012
This paper investigates one issue related to Large Eddy Simulations (LES) of self- excited combustion instabilities in gas-fueled swirled burners: the effects of incom- plete mixing between the gas injection and the combustion chamber.

Vibration of a flexible pipe conveying viscous pulsating fluid flow [PDF]

open access: yes, 2000
The non-linear equations of motion of a flexible pipe conveying unsteadily flowing fluid are derived from the continuity and momentum equations of unsteady flow. These partial di!erential equations are fully coupled through equilibrium of contact forces,
