Macromolecular Symposia, EarlyView.ABSTRACT This study aims to validate the structural and thermomechanical reliability of an additively manufactured test chamber specifically designed for the experimental investigation of sustainable aviation fuel (SAF) atomization under jet‐in‐crossflow (JICF) conditions representative of gas turbine afterburners. The proposed test chamber is designed

Lagrangian Statistics of Heat Transfer in Homogeneous Turbulence Driven by Boussinesq Convection
Fluids, 2020 The movement of heat in a convecting system is typically described by the nondimensional Nusselt number, which involves an average over both space and time.

High-Reynolds number calculations of turbulent heat transfer in FlowVision software [PDF]
Компьютерные исследования и моделирование, 2018 This work presents the model of heat wall functions FlowVision (WFFV), which allows simulation of nonisothermal flows of fluid and gas near solid surfaces on relatively coarse grids with use of turbulence models.

Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT The planar and radial thermal free jets for forced convection of a non‐Newtonian power‐law fluid are investigated. The thermal diffusivity is dependent on the shear‐rate and is not a constant. The flow in planar and radial thermal free jets is governed by the momentum, continuity and energy balance equations. In the stream‐function formulation,

Numerical Simulation of Turbulent Channel Flow at Low Prandtl Number [PDF]
, 2016 Liquid metals are primary coolants in Generation IV nuclear reactors. For low Prandtl\ud fluids, such as liquid metals, classical Reynolds analogy of using turbulent Prandtl number\ud close to unity doesnt predict heat transfer characteristics ...

Quarterly Journal of the Royal Meteorological Society, EarlyView.A theory for the interaction between a boundary layer and a low mountain is used to provide estimates of the turbulent orographic form drag, upward‐propagating mountain gravity‐wave drag, and trapped lee‐wave drag (case shown in the figure). After reviewing briefly how these processes are represented in weather and climate models, we propose a ...

MODELING HEAT EXCHANGE DEPENDING ON THE PRANDTL NUMBER FOR VARIOUS GEOMETRIC AND REGIME PARAMETERS
Вестник Дагестанского государственного технического университета: Технические науки, 2020 Objectives. The aim is to study the dependency of the distribution of integral heat transfer during turbulent convective heat transfer in a pipe with a sequence of periodic protrusions of semicircular geometry on the Prandtl number using the calculation ...

High Voltage, EarlyView.ABSTRACT The breathing system of an oil‐immersed transformer is of vital importance for maintaining equilibrium between internal and external pressures, with any malfunction potentially disrupting the transformer's stable operation. This study develops a thermal–fluid–structure interaction (TFSI) model to simulate the breathing phenomenon in a 110 kV ...
