The process of direct steam generation was studied in this work
within a parabolic trough solar collector in order to generate
electricity. The study was based on the equations of a two phase
flow to study heat transfer in the collector's tube. Th
e study showed
a possibility to reach an effective model to study the performance of
this type of solar collectors which will aid in the understanding of
the working principle of power plants and to research further
towards new control strategies of solar power plants or towards the
hybridization with other types of power plants.
The high levels of groundwater at riparian rivers or lakes adversely
affect the foundations of the engineering facilities which established
in these areas, in terms of the corrosion of the reinforced concrete of
the foundations, and on the other h
and the difficulty of doing the
engineering work required. Therefore it is necessary to reduce the
levels of groundwater beneath the level foundation. In this research,
the groundwater movement toward two coastal drains located at
different levels has been studied numerically.
The purpose of this research is to study and create a stochastic mathematical model
based on a renewable energy source (wind).
The question of finding optimal values for the variables of the mathematical model
subject to stochastic conditions is one of the random mathematical problems, which require
special stochastic methods to solve in the general case.
The purpose of research is the study and analysis of some of the stochastic semi-gradient methods and their applicability to find the optimal solution for the issues of optimization are subject to the effects Random and conditions are controlled by c
hance, as we proved the convergence of some of these mathematical methods and their effectiveness for some of the issues of stochastic non-convex and equipped objective function and specific constraints and where taken energy complex solar as an example
The purpose of this research is to study and create a mathematical model under the terms of the probability of randomly imposed, specially by building a model of random Complex Solar particular by removing the salinity of the water, and thus to obtai
n fresh water and that, under certain conditions.
We Assure that the question of finding the optimum values for the variables solar collector above represent varieties of special issues of mathematical modeling and nonlinear stochastic, we point to that the most effective ways to find the perfect solution for this kind of issues are stochastic gradient methods
