The study of electromagnetism in electrical machines is critical, especially in the field of design, investment and optimal performance. To achieve this, there are many ways in which varying degrees of accuracy . The main aim of this piece of resea rch is to study electromagnetic fields distribution in 3ph-induction machines using computational numerical methods and proper software, because these fields form the basic principle in machine 's work. It has been used the finite element method aided computer to solve magnetic equations (Maxwell equations). The simulation of magnetic field in induction machine performed by ANSYS-software. The paper shows technique for finding the electromagnetic fields distribution in all parts inside 3phinduction machine to get optimal design.
This research deals with analytical study of exterior Beam-Column connections behavior under seismic load. Tow parameters were considered: axial load on the column and confinement of joint region with stirrups. Ansys program was used to analytica l study of three types of exterior Beam-Column connections under cyclic load. The results were shown a good agreement with general behavior of three types. The analytical results indicate that the tow parameters will improve the behavior of the connections delay cracking at joint core and increasing connection stiffness in rotation and displacement with decreasing shear value at joint.
In this research an absorptive cooling cycle system modeling which can be used for conditioning purposes by using EES program was done. By using this program, the effect of temperature of the vapor generator, the evaporator and the condenser on the p erformance of the vapor cycle and the circulating coefficient was studied as well as the effect of the evaporating range width in the generator and the definition the values and ideal ranges for each part. The result showed that whenever the condenser temperature increases the performance coefficient ( COP ) decreases, and by increasing the condensation temperature from 18 – 36 C , thus the values of the circulating coefficient increases, while the average temperature released from the condenser to the external environment decreases at the same range of the previous temperature, and that the increase of the evaporator temperature would increase the performance coefficient ( COP ). An absorptive cooling circuit system modeling using water and lithium bromide was achieved. Results showed that the increase of the evaporator temperature of between 4 -13 C, the average of heat amount drawn from the desired place to be cooled would increase.
This research aims to check the actual performance of the work of the propeller depending on series of results issued from Hamburg basins that are known by RANSE where the arcs analysis and the hydrodynamic characteristics of the propeller work in open water are done by using the commercial program CFD Analysis m by Hydro Comp. Thus, the results were compared with the experimental data and the study of fluently around the different parts of the ship and the definition of resistance values and friction factor CF. These values were compared with those issued by ITTC basins and coincidence was found between those of RANSE and the experimental values in the different stages of study. Therefore, a collection of solutions related to the work of propeller were achieved in addition to the evaluation of the level of interaction and the exchanged effect of the propeller work in different conditions, and the definition of degree of difference resulted from the values of the rotation moment and the factors of advance and control the are resulted from the use of CFD program. The numerical results and the syntheses data were discussed in case of working in open water.
The quick consuming of products and the strong competition between producers caused to increase the complexity of products, so the digital factory became a need between design and producing actually to achieve a production system with a shorter ti me and optimal design and parameters without engineering modifications. This research offering a reference model basing on a complete framework between the engineering applications to build a computational model with a single core based on the integration between three dimensions modeling and automation of application for digital factory concept, to optimize the design of achieving the ideal execution of actual production system. Where we achieved the control of three-dimensional computer model according to process automation exactly as in actual through integrating tools, where the percentage of exact between the real factory and digital factory was 83% by using the time of process as the main factor for comparison in this evaluation.
