Variable Turbulent Schmidt and Prandtl Number Modeling
Engineering Applications of Computational Fluid Mechanics, 2010 Abstract:This paper describes variable turbulent Schmidt and Prandtl number formulations, based on Rodi’s (1980) algebraic Reynolds stress model adapted to velocity-scalar correlations. Since the approach is algebraic in nature, it does not introduce transport equations beyond the ones already existing to compute the flow, rendering it a viable ...

Water Resources Research, Volume 62, Issue 6, June 2026.Abstract Hydrodynamics characteristics in the mainstem–tributary confluence profoundly affect the local environment and ecology. Thermal stratification widely occurs in large reservoirs, and the need to investigate hydrodynamics of mainstem–tributary confluences is urgent. Moreover, selective withdrawal is often used to regulate the outflow temperature,

Scaling in large Prandtl number turbulent thermal convection
, 2002 We study the scaling properties of heat transfer Nu in turbulent thermal convection at large Prandtl number Pr using a quasi-linear theory. We show that two regimes arise, depending on the Reynolds number Re. At low Reynolds number, $Nu Pr^{-1/2}$ and Re

Integrating a Three‐Dimensional TKE‐Based Subgrid Diffusion Scheme Into GFDL FV3
Journal of Advances in Modeling Earth Systems, Volume 18, Issue 6, June 2026.Abstract We present the implementation of an inline three‐dimensional (3D) turbulent kinetic energy (TKE)‐based subgrid diffusion scheme in the Geophysical Fluid Dynamics Laboratory (GFDL) Finite‐Volume Cubed‐Sphere (FV3) dynamical core. This scheme addresses the need for a unified and physically grounded treatment of turbulence as FV3 is increasingly ...

, 2013 In this thesis I study a variety of two-dimensional turbulent systems using a mixed analytical, phenomenological and numerical approach. The systems under consideration are governed by the two-dimensional Navier-Stokes (2DNS), surface quasigeostrophic

Journal of Applied Fluid Mechanics, 2018 In this paper, we presented a similarity solution for turbulent film condensation of stationary vapor on an isothermal vertical flat plate. In this method, some similarity transformations are employed and the set of governing partial differential ...

Global Change Biology, Volume 32, Issue 6, June 2026.Tropospheric ozone (O3) is a phytotoxic air pollutant. The stomatal uptake of O3 is a substantial sink of O3, but it can create oxidative stress within plants, reducing photosynthesis and crop yields. In seasonally dry climates, stomatal regulation causes temporal decoupling between stomatal conductance and atmospheric O3 concentrations protecting ...

Cio-cio-san no Yūutsu: memoirs of magnetogenesis and Turbulent Dynamo Theory
, 2013 The origins of cosmic magnetic fields are not as yet well understood. In this dissertation we investigate, via direct numerical simulation, the temporal evolution and behaviour of magnetic fields that are generated from absolute zero initial conditions ...

Turbulent natural convection along a vertical plate for different Prandtl number fluids
, 2020 The design of Liquid Metal cooled reactors relies on Computational Fluid Dynamics (CFD) to evaluate the operational conditions and safety of the reactor. Liquid metals presents a very low Prandtl number value Pr≈O(0.001-0.01). Modeling the turbulent heat

Experimental heat/mass transfer studies of turbulent wall-bounded jets associated with mechanicallly ventilated enclosures [PDF]
, 1986 The development and use of a'n experimental test rig is reported which is capable of modelling two- and three-dimensional wall-bounded air jets. This test rig was primarily produced in order to facilitate the experimental verification of computer ...
