A three - Dimensional numerical simulation of shut - Down heat transfer process in overhead waxy crude oil pipeline

Case Studies in Thermal Engineering, 2020
An additional specific heat capacity method and a momentum source method are used to establish a mathematical model to numerically simulate the three-dimensional heat transfer characteristics and flow characteristics of the horizontal three-dimensional ...

The Distribution of the Thermal Field in an Elliptical Electric Conductor Coated with Insulation

Energies, 2021
The paper determines the stationary thermal field in an elliptical cross-section electric conductor coated with insulation. Heat is generated by the flow of alternating current (AC) through the conducting core, and then dissipated from the insulation ...

Microscale engine swimming underwater powered by Marangoni convection

Journal of Thermal Science and Technology, 2016
This study proposes a prototype of a microscale engine swimming underwater powered by Marangoni convection. The engine is a layered disk with a hole and holds a bubble ring in a gap between the layers.

A large-scale layered stationary convection of an incompressible viscous fluid under the action of shear stresses at the upper boundary. Velocity field investigation

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2017
The exact solution of the definition of convective motions in a layered large-scale flows of a viscous incompressible fluid in a steady case is considered. It was shown that the received problem is, firstly, overdetermined and, secondly, a nonlinear (due

Natural convection and the evolution of a reactive porous medium [PDF]

, 2011
We describe a mathematical model of buoyancy-driven flow and solute transport in a saturated porous medium, the porosity and permeability of which evolve through precipitation and dissolution as a mineral is lost or gained from the pore fluid. Imposing a

Retrieval and Experiments of Atmospheric Vertical Motions in Convective Precipitation Clouds

应用气象学报, 2022
Detecting the vertical motions of the atmosphere in convective clouds is difficult. The cost of aircraft detection is expensive, limited by maximum flight altitude, high detection risk, low frequency, etc.

Topothermohaline convection – from synthetic simulations to reveal processes in a thick geothermal system [PDF]

Hydrology and Earth System Sciences
The water table topography, temperature, and solute content of groundwater all influence regional groundwater flow. Two-dimensional synthetic numerical calculations were performed to investigate the dynamic interaction between topography-driven forced ...

Interior Structures and Tidal Heating in the TRAPPIST-1 Planets [PDF]

, 2018
With seven planets, the TRAPPIST-1 system has the largest number of exoplanets discovered in a single system so far. The system is of astrobiological interest, because three of its planets orbit in the habitable zone of the ultracool M dwarf.
