Prandtl Number of Toroidal Plasmas [PDF]

Prandtl Number of Toroidal Plasmas
Theory of the L-mode confinement in toroidal plasmas is developed. The Prandtl number , the ratio between the ion viscosity and the thermal conductivity is obtained for the anomalous transport process which is caused by the self-sustained turbulence in ...

A Model for Eddy Conductivity and Turbulent Prandtl Number

, 1973
This paper presents a model for eddy conductivity and turbulent Prandtl number based on the considerations of a Stokes-type flow. The expressions obtained by the model provide continuous velocity and temperature distributions for turbulent flows and are ...

Capability and Limitations of a Tuned Mass Damper for a 15‐MW Semisubmersible Floating Wind Turbine

Wind Energy, Volume 29, Issue 11, November 2026.
ABSTRACT Large floating offshore wind turbines (FOWTs) under coupled aerodynamic and hydrodynamic loading exhibit broadband low‐frequency response in addition to the platform‐pitch resonance. Tuned mass dampers (TMDs) have been studied for a range of applications, but their net benefit under fully coupled operational conditions has not been quantified.

Computational Role in Thermal Engineering and Chemical Analytics During the Rotating Disk of Generalized Williamson Viscosity and Thermal Conductivity

Advanced Physics Research, Volume 5, Issue 10, October 2026.
The schematic diagram shows the flow configuration of the model. The swirling flow of shear‐thinning materials is significantly investigated under the influence of mixed convection. In addition, heat and mass transfer flow characteristics along with gyrotactic microorganisms is also investigated. ABSTRACT Thermal conductivity, temperature gradient, and

Numerical modeling of thermophoresis and Brownian with heat transfer in shear-rate-dependent fluid: The finite element simulations

Case Studies in Thermal Engineering
This article discusses the simultaneous influence of thermophoresis, Brownian motion, and the dispersion of nanoparticles on thermal enhancement in non-Newtonian fluid existing over a surface stretching with non-uniform velocity.

Heat transfer in drop-laden low-Prandtl-number channel turbulence [PDF]

In this work, we numerically investigate heat transfer in low-Prandtl-number drop-laden wall-bounded turbulence. These flows are characteristic of nuclear and fusion technologies, where liquid metals - known for their high thermal conductivity - are ...

Optimized Wavy Thermal Radiative Analysis of Electrochemically Ternary Hybrid Nanomaterials Affected by an Induced Magnetic Force: An ANN‐Based Levenberg–Marquardt Backpropagation Approach

Advanced Physics Research, Volume 5, Issue 10, October 2026.
This diagram illustrates the wavy flow configuration of the model in a Cartesian coordinate system. It represents the heat and mass transfer characteristics of ternary hybrid nanofluids over a vertically wavy surface in the presence of an induced magnetic field and double‐diffusive mixed convection.

An asymptotic solution for large Prandtl number free convection

, 1968
The set of ordinary differential equations governing free convection boundary layer flow past an isothermal semi-infinite vertical flat plate is solved for large Prandtl numbers by means of the method of matched asymptotic expansions.

Nanotechnology‐Driven Analysis of MHD Maxwell‐Casson Nanofluid Flow With Activation Energy Using Artificial Neural Networks

Engineering Reports, Volume 8, Issue 10, October 2026.
This study investigates Casson nanofluid flow over a porous inclined plate under magnetic field, thermal radiation, buoyancy, and chemical reaction with activation energy. A feedforward artificial neural network (ANN) is employed to solve the coupled nonlinear governing equations and predict velocity, temperature, and concentration profiles.

RSM‐Based Optimization and Sensitivity Analysis of Radiative MHD Tangent Hyperbolic Nanofluid Flow Over an Exponentially Stretching Porous Sheet With Variable Heat and Mass Fluxes

Engineering Reports, Volume 8, Issue 10, October 2026.
The viscous flow of an incompressible hydromagnetic tangent hyperbolic nanofluid over an exponentially stretching porous sheet is investigated, incorporating variable heat and mass fluxes, Brownian motion, thermophoresis, and thermal radiation. Governing PDEs are transformed into ODEs via similarity transformations and solved numerically using MATLAB's
