Forced linear shear flows with rotation: rotating Couette-Poiseuille flow, its stability and astrophysical implications [PDF]
, 2021 We explore the effect of forcing on the linear shear flow or plane Couette flow, which is also the background flow in the very small region of the Keplerian accretion disk. We show that depending on the strength of forcing and boundary conditions suitable for the systems under consideration, the background plane shear flow and, hence, accretion disk ...

Interphase Mechanical Energy Transfer of Gas-Liquid Flow in Variable Cross-Section Tubes
Journal of Marine Science and Engineering, 2023 The use of gas energy includes a wide range of applications to directly accelerate the liquid in a pipeline without the aid of mechanical equipment, such as marine gas-liquid jet propulsion. To clarify the characteristics of energy transfer by interphase

Two-phase discharge flow prediction in safety valves [PDF]
, 2012 Safety Relief Valves (SRV) are necessary elements in the protection of any pressurised system and the prediction of the expected discharge flows is an important consideration for the valve sizing to ensure that rupture pressures do not occur.

Classification of instabilities in parallel two-phase flow [PDF]
, 1996 There is extensive literature on the stability of parallel two-phase flow, both in the context of liquid-liquid as well as gas-liquid flow. Aimed at making this literature more transparent, this paper presents a classification,scheme for the various ...

A Curvature Flow Unifying Symplectic Curvature Flow And Pluriclosed Flow [PDF]
Pacific J. Math. 277 (2015) 287-311, 2013 Streets and Tian introduced pluriclosed flow and symplectic curvature flow in recent years. Here we construct a curvature flow to unify these two flows. We show the short time existence of our flow and exhibit an obstruction to long time existence.
