Adsorption Cycle

The present work is devoted to the study of the processes of heat and mass transfer in the adsorbers of the preliminary drying unit of the atmosphere purification system. A mathematical model has been developed that adequately reflects the physical processes at all stages of the adsorption cycle.Algorithms for solving problems and programs for calculating heat and mass transfer processes in an adsorption regenerated installation are obtained, results of parametric calculations of heat and mass transfer processes at each stage of the adsorption cycle and for the entire cycle as a whole are obtained.

The Mathematical Model

The mathematical model of heat and mass transfer processes in the combustion chamber of diesel generator units with valve inductor generators has been developed. The mathematical model takes into account the actual geometry of the combustion chamber and the operating conditions of the diesel engine. A study of the main characteristics of a diesel generator in a wide range of modes of operation has been carried out. In addition to energy characteristics, environmental parameters have been considered

Optimal Calculation

The article highlights the optimal calculation methods for determining the parameters of heat and mass transfer processes occurring in the rotary-vane engine with an external supply of heat. It is shown that the mathematical model of working processes must consist of two parts. One part describes the processes occurring in the isolated volume. The second part describes the processes of mass exchange between the working chambers of two modules, as well as a heater or a cooler.

The Mathematical Model

Abstract The generic mathematical model and computational algorithm considering hydrodynamics, heat and mass transfer processes during casting and forming steel ingots and castings are offered. Usage domains for turbulent, convective and non-convective models are determined depending on ingot geometry and thermal overheating of the poured melt. The expert system is developed, enabling to choose a mathematical model depending on the physical statement of a problem.

High Viscosity Oil

In order to solve scientific and engineering problems arising during analysis and development of hard-to-recover hydrocarbon reserves in high-viscosity oil deposits, we performed a numerical study of heat and mass transfer processes in a mixture of water and oil. We achieved these goals by developing a hydrodynamic and thermophysical model of non-steady-state quasi-three-dimensional heat and mass transfer in a stratum featuring a system of horizontal wells. We propose an analytical approach to plotting a dynamic computational grid in a natural semi-fixed coordinate system. We compute streamlines and equipotential lines using the analytical solution proposed, which is based on complex analysis. The object of our investigation is natural strata saturatedby a multiphase fluid. We used the physical and mathematical model and the calculation method proposed to develop a software package and conduct a series of numerical and parametric studies concerning the effects caused by thermophysical properties of rocks and fluids combined with various operation modes in a system of horizontal wells. The paper describes how these parameters affect the rate of oil production in a real high-viscosity oil deposit. We verified the results obtained against actual core sample investigation data and technological parameters of oil deposit development, and further compared them to known analytical solutions and commercial hydrodynamic simulators
