Renewable energy sources are becoming more and more popular, regarding the pollution and non-sustainability of common energy sources. Photovoltaic is the most direct way to convert solar radiation into electricity using the photovoltaic effect. This technology generates direct current (DC) electrical power from semiconductors when they are illuminated by photons. This paper presents a mathematical model in CFD that simulates the thermal presentation of a solar thermal photovoltaic panel equipped with circler, square and elliptic pin fin cooling module. The effect of cooling water velocity on photovoltaic panel average temperature and average cooling water temperature has been studied and the effect of cooling water velocity on photovoltaic panel average temperature and average cooling water temperature. The results show that velocity contours for water flows in circular, elliptic and square pin fin cooling module with inlet water velocities (0.0002, 0.0004 and 0.001 m/s). It is noticed that for square pin fin, the velocity between the pins is higher than the other types of pins, which leads to more circulation of water and more cooling.

With the beginning of 2020, the Corona virus pandemic began, which negatively affected all of humanity, as medical and engineering research began to solve many problems faced by society during the era of the virus. Those who are exposed to this situation are among the medical staff responsible for treating and quarantining patients with the Corona virus. It has become the responsibility of engineers to develop solutions to the ventilation problem in order to limit the spread of this virus. Where the aim of this research paper was to study the effect of distance between patient and nurse and the effect of ventilation on the spread of the Corona virus. where a simulation model was created a room with real and 3D dimensions was studied with a patient lying down and the nurse treating him next to him. Where the room contains an air conditioner, two outlets for the airflow and an opening for the patient's mouth to simulate the exit of carbon dioxide gas from his mouth. Where the different and high speeds were studied to find out their effect on the spread of the virus abroad and its disposal. The result proves the best flow velocity of the ventilation system is 20 m/s, which led to a large limitation of the waiting for the Corona virus. The best place for the patient and the airway in the room should not be in the same airway, and the best place is between them. where these results serve as a reference for the engineering of medical rooms in terms of the effect of ventilation and distance of the pathogen on the spread of the Corona virus.

There are several applications in the aerospace, automotive and energy industries, for example, that often require high fidelity modeling or problems involving structural mechanics, heat transfer, or electromagnetic. Finite element analysis (FEA) is a popular method for solving the underlying partial differential equations (PDE) for these problems. 3D finite element analysis or 3D-FEA accurately captures the physics of these problems. The relevance of this study is to show how to set up finite element analysis (FEA) simulations and leverage the model of the environment to solve problems typically encountered by engineers and scientists in a variety of fields such as aerospace, automotive and energy. This study analyzes the behavior of mechanical components under different physical effects and shows a thermal analysis of a commercial KUKA YouBot robotic arm component by finding temperature distributions, figures, code, and test results for multiple materials. The developed model allows understanding and assessing the responsive component under loading, vibration or heat and determining deformation stresses among many things to select the best material and even prevent failure or undesired resonance as an example. These systems are typically modeled using partial differential equations or PDEs that capture the underlying physics of the problem and FEA is just one of the most common methodologies to solve this type of equation. The linear regression model can be a good predictive model that represents the relationship between thermal conductivity and max temperature to avoid undesired performance of the robotic arm.

This work deals with fluid-structure interaction (FSI), one of the emerging areas of numerical simulation and calculation. This research shows a numerical study investigating heat transfer enhancement and fluid-structure interaction in a circular finned tube by using alumina nanofluid as a working fluid with a typical twisted tape that has a twisting ratio of 1.85. The studied nanofluid volumes of fraction are φ=0, 3, 5 % under conditions of laminar and turbulent flow. The solution for such problems is based on the relations of continuum mechanics and is mostly done with numerical methods. FSI occurs when the flow of fluid influences the properties of a structure or vice versa. It is a computational challenge to deal with such problems due to complexity in defining the geometries, nature of the interaction between a fluid and solid, intricate physics of fluids and requirements of computational resources. CFD investigations were made based on the numerical finite volume techniques to solve the governing three-dimensional partial differential equations to get the influence of inserted twisted tape and concentration of nanofluid on heat transfer enhancement, friction loss, average Nusselt number, velocity profile, thermal performance factor characteristics, and two-way interaction in a circular tube at laminar and turbulent flow. The governing continuity, momentum and energy transfer equations are solved using Ansys Fluent and Transient Structural. The simulation results show that the deformations of two-way coupling fluctuate from side to side, with 0.004 mm, as maximum amplitude, located at the typical twisted tape center. Heat transfer dissipation improved by adding fins and as Reynolds numbers increase the heat transfer behavior increases.

The heat and mass transfer in a solar still with a single cover angle located in Baghdad has been investigated experimentally in order to increase its efficiency and productivity. The experimental setup was fabricated using a galvanized iron sheet, with all of its sides are made from the same material and covered by a transparent glass of a 3 mm thickness. To reduce the vapor leakage to the surroundings, the solar still was sealed. The experimental tests were carried out for several months from January to June. The effect of concentrator, and the coal and chemical additives on the performance and productivity of the solar still were studied at the same time. Three depths (1, 2 and 3 cm) within the basin were tested to investigate the influence of water depth on the still productivity in close weather conditions. The experimental data indicated that the productivity and the efficiency of the still increased by 40% and 37%, respectively, in comparison with still without concentrator, and the productivity and the efficiency increased by 14% and 16%, respectively using Metilen blue. Through the study, it was noted that the reduction in the depth of the water in the basin distiller leads to an increase in the productivity and efficiency of the solar still.
