New geophysical complex-field approach to modelling dynamics of heat-mass-transfer and ventilation in atmosphere of the industrial region

Abstract

New generalized approach, including an improved theory of atmospheric circulation in combination with the hydrodynamic model (with correct account of turbulence in atmosphere of the urban area) and the Arakawa-Schubert method of calculation of cloud convection and theory of complex geophysical field is applied to the simulation of heat and air transfer in atmosphere of industrial region. The modelling ventilation data (mesocirculation) parameters over territory of Odessa, as well as the area of the Fukushima power plant after 2011 accident are presented.

Advanced Photochemical Box and Quantum-Kinetic Models for Sensing Energy, Radiation Exchange in Atmospheric Gases Mixtures and Laser- Molecules Interaction

“…The physical features of air ventilation predetermine the necessary modification of the well-known Arakawa-Schubert model. The model includes the budget equations for mass, moist static energy, total water content plus the equations of motion [2,13]:…”

“…[11,12] it is presented a new generalized approach, including an improved theory of atmospheric circulation in combination with the hydrodynamic model (he Arakawa-Schubert method of calculation of cloud convection and theory of a complex geophysical field is applied to the simulation of heat and air transfer in atmosphere of industrial region. In this paper we present a set of advanced photochemical box models (APBM) with the inclusion of a submodel of the boundary layer using complex plane field methods [2,[13][14][15][16]) and spectral algorithms with optimized blocks describing nonlinear radiation transfer and chemical conversion mechanisms [11,12], quantum-kinetic and photoelectronic models for describing nonlinear optical effects due to the interaction of infrared laser radiation with the gas atmosphere of an industrial city..…”

New theoretical approach to dynamics of heat-mass-transfer, thermal turbulence and air ventilation in atmosphere of an industrial city

“…Disadvantages of these approaches are well known and became very critical if the atmosphere contains elements of convective instability. In our previous papers [7,[15][16][17][18] we have developed an advanced approach to the simulation of heat and air ventilation in atmosphere of an industrial region (so called local scale atmospheric circulation complex-field (LACCF) approach). The approach includes an improved theory of atmospheric circulation in combination with the hydrodynamic forecast model (with quantitatively correct account of turbulence in the atmosphere at local scales) and the Arakawa-Schubert model of cloud convection.…”

“…As usually, we attribute the movement to the polar coordinates (r, θ) in the area located within the zone of action of the thermal "cap" (or "heat island") of the city [7]. Flowchart of the ventilation over the urban region territory by air flows in a presence of the cloud's convection is presented in Figure 1 and explains the key physical processes [16].…”

“…The vertical rise of the impurity is calculated by the formula (2b). [16][17][18], an air flux speed over a city's periphery in a case of convective instability can be found by method of plane complex field theory (in analogy with the Karman vortices chain model) [6,19]:…”
