چکیده

Regional models that describe the spatial-temporal variability of atmospheric aerosol parameters are necessary to solve many radiative and climatic problems. An important area of study is the content of the main absorbing substance, soot (black carbon), in aerosol particles. Soot determines the nonselective absorption of radiation in the visible wavelength range by aerosol. It is an important radiativeclimatic factor because of its significant effect on the atmospheric transparency, albedo of clouds and snow cover.

Three Dimensional Laminar Convection Flow of Radiating Gas over a Backward Facing Step in a Duct

In this study, three-dimensional simulations are presented for laminar forced convection flow of a radiating gas over a backward-facing step in rectangular duct. The fluid is treated as a gray, absorbing, emitting and scattering medium. The three-dimensional Cartesian coordinate system is used to solve the governing equations which are conservations of mass, momentum and energy. These equations...

Numerical simulation of a three-layered radiant porous heat exchanger including lattice Boltzmann simulation of fluid flow

This paper deals with the hydrodynamic and thermal analysis of a new type of porous heat exchanger (PHE). This system operates based on energy conversion between gas enthalpy and thermal radiation. The proposed PHE has one high temperature (HT) and two heat recovery (HR1 and HR2) sections. In HT section, the enthalpy of flowing high temperature gas flow that is converted to thermal radiation em...

Effects of absorbing aerosols in cloudy skies: a satellite study over the Atlantic Ocean

We present a method for deriving the radiative effects of absorbing aerosols in cloudy scenes from satellite retrievals only. We use data of 2005–2007 from various passive sensors aboard satellites of the “A-Train” constellation. The study area is restricted to the tropicaland subtropical Atlantic Ocean. To identify the dependence of the local planetary albedo in cloudy scenes on cloud liquid w...
