Mathematical Modeling of Surface Heat Flux During Quenching
Metallurgical and Materials Transactions B, 2009In this article, a method to model the heat flux during quenching has been developed to bring out the effect of initial soaking temperature. Quench probes with a diameter of 20 mm and a length of 50 mm were prepared from 304 L stainless steel. These probes were quenched from different initial soaking temperatures ranging from 400 °C to 950 °C in water.

A model for the net total radiation flux at the surfaces of a building
Building and Environment, 1981Abstract A model is presented for the net total radiation flux at the surfaces of a particular building (in the shape of a U) which can be adjusted to other building shapes. The first step in deriving this model consists in the calculation of the various shape factors under which each surface sees the adjacent surfaces or the sky.

Single- and Dual-Source Modeling of Surface Energy Fluxes with Radiometric Surface Temperature
Journal of Applied Meteorology, 1996Abstract Single- and dual-source models of the surface energy transfer across the soil-vegetation-atmosphere interface were used in conjunction with remotely sensed surface temperature for computing the surface energy balance over heterogeneous surfaces.

Attribution of trends in modeled and observed surface water fluxes
Evaporation and runoff are the major surface water fluxes. Together they determine water availability on land, which ecosystems and humans rely on. The mechanisms driving trends in evaporation and runoff in the context of global change are not fully understood, which is also reflected in a significant uncertainty of projections of these water fluxes ...Josephin Kroll +3 more

An extended rational thermodynamics model for surface excess fluxes
Physica A: Statistical Mechanics and its Applications, 2012In this paper, we derive constitutive equations for the surface excess fluxes in multiphase systems, in the context of an extended rational thermodynamics formalism. This formalism allows us to derive Maxwell–Cattaneo type constitutive laws for the surface extra stress tensor, the surface thermal energy flux vector, and the surface mass flux vector ...

Journal of Geophysical Research: Atmospheres, 1995
Land surfaces with fractional vegetation cover possess distinctive micrometeorological properties that complicate the use of energy balance models to simulate surface fluxes. The use of thermal infrared (TIR) measurements to drive surface energy balance models over such surfaces is further complicated because TIR sensors view both soil and canopy ...
