Extensive computational fluid dynamics (CFD) simulations were conducted to study “rimming” flow in a partially filled horizontally rotating cylinder. These flows are encountered …
S Khanum, N Tiwari - Physical Review Fluids, 2020 - APS
Stability analysis of gravity-driven flow of a thermoviscous liquid on the exterior surface of a uniformly heated or cooled vertical cylinder is presented. The film evolution model derived …
The thermocapillary instabilities of the liquid layers on an inclined plane with zero heat flux are examined by linear stability analysis. There is an angle between the gravity and the …

The present study investigates the flow of a thin film inside a uniformly heated/cooled cylinder rotating at various inclinations. The governing equations for mass, momentum, and …
G Singh, N Tiwari - Physical Review Fluids, 2024 - APS
A liquid film coating a cylindrical substrate is unstable to interfacial disturbances governed by Rayleigh-plateau instability. These initial disturbances grow in time and, beyond …
D Kishal, N Tiwari - Journal of Engineering Mathematics, 2022 - Springer
A thick film flow on a non-isothermal vertical cylinder due to gravity is analyzed for temporal and spatiotemporal stability. The model equation is derived by neglecting inertial terms and …
The transient growth in thermocapillary liquid layers is examined by nonmodal stability theory. Two kinds of thermocapillary liquid layers including linear flow and return flow are …
D Kim, HS Shim, G Ryu, J Kim, J Lee - European Journal of Mechanics-B …, 2022 - Elsevier
In rotary tube reactors, rotary evaporators, or rotary atomizers, liquid is transported through a partially filled axially rotating pipe. The flow is annular when the pipe rotation is fast enough …
