The author takes the opportunity to express immense gratitude to respected research work advisor Prof. B. K. Mandal & Prof. A. K. Chowdhuri, Department of Mechanical Engineering, Bengal Engineering & Science University, Shibpur, Howrah-711103 for their guidance, encouragement and motivation towards real-time study right from the beginning of the research up to the completion of the study. I express deep respect to all the faculty members of the department for their inspiration and help during the entire period of this study. I am also thankful to departmental technical staffs and all non-teaching staff of Mechanical Engineering Department who in some way or other helped and encouraged me during the study. I express my heartiest thanks to Shri Ambarish Datta, Shri Achinta Sarkar and Shri Pradip Mondal, for their co-operation during the work. I would like to thank those persons whose name could not figure here, once again for their valuable guidance, support and kind attention given to me throughout the project work. Finally I bow to my parents, my all-family
