Analytical and Numerical Simulation of Shell and Tube Heat Exchanger

Abstract: Shell and tube heat exchanger is the most common type of heat exchanger and widely used in oil refinery and other large chemical processes because it suite for high pressure application. In this project design of shell-and-tube heat exchanger is developed using analytical method. Then the CFD simulation will be carried out. Computational Fluid Dynamic (CFD) is a useful tool in solving and analysing problems that involve fluid flows, in this process in solving the simulation consist of modeling and meshing the basic geometry of shell and tube heat exchanger using the CFD package ANSYS Meshing Then, the boundary condition will be set before been simulate in Fluent 12.1 based on the analytical parameters. Then the CFD simulation of heat transfer in shell and tube heat exchanger model is validated against analytical method. Finally the optimization of baffle will be carried out to improve the stagnant zone and heat transfer in the segmented Shell and Tube Heat Exchanger.

Paper Title:

Genetic Algorithm for Optimization using Genealogy Plots to Investigate the Influences of Heat Input Ratio on Burn - Through Prevention at a GTAW Process

Abstract:  Gas Tungsten Arc Welding (GTAW) offers a variety of shielding gas for joining different steel plates with different thicknesses. It is a technique that enhances the service performance of welded joints using different gas flow rate values so as to have comparison between the joints made. To avoid weld burn-through, excessive heat input and too high welding current must be regulated at a GTAW process so as to  control welding current and achieve a sufficient heat input that  will prevent weld burn-through and produce quality welds free from spatter. During welding, escape of gas when prevented, will produce clean joints, slow cooling (allows gases to escape) and proper shielding (absorbing the gases C02, N2 and H2 from the atmosphere). This paper investigates burn-through prevention in welds produced, using Genetic Algorithm (GA) for optimization using genealogy plots to study the influence of Gas Flow Rate (F) ,welding current and heat input ratio on burn-through in welds. Genetic Algorithm was used for optimization in order to reach optimal solution after satisfying constraints used. In order to alleviate the problem that burn -through defect poses on welds, a matrix design was developed to determine the experimental results obtained and the results were applied to the GA model for optimization in order to obtain optimal values of responses as well as optimal values of input process parameters. Genealogy plots were used to validate the model. The genetic algorithm optimization results showed that the gas flow rate should be set to 17.67 lit/min for optimum input process parameter value. Heat input ratio optimal values of 21.96KJ/min and welding current optimal value set at 167.3 amperes were established.

Paper Title:

Abstract: Medical image retrieval based on its visual attributes is one of the prime aspects for the clinical decision making process. It can be beneficial and important to find other images of the same modality, the same anatomic region in disease identification. This results in improved healthcare system with increased efficiency. In this paper we proposed a model of medical image retrieval system that works on the features extracted from transformed coefficients by applying four different transformations viz. Discrete Fourier Transform (DFT), Discrete Sine Transform (DST), Discrete Cosine Transform (DCT) and Discrete Wavelet Transform (DWT). Visual content of X-Ray images better expressed with textural features. The texture attributes computed from transformed domain shown superior performance over spatial domain computed GLCM matrix based features. So in this paper we presented the comparison analysis of the four transformation techniques, DFT, DST, DCT and DWT in analyzing the performance of medical image retrieval system. IRMA 2009 X-Ray image database was used for experimentation. X-Ray image retrieval worked well with regionally computed attributes over global features, transform coefficients computed by partitioning the images into 64 regular regions of 16 x 16 in size. Images retrieved by finding the similarity between the region wise feature vectors. Among the four transformations, DWT and DCT result with more than 75% Mean Average Precision (MAP) at 100% recall rate.
