This book is a collection of selected research papers from the 14th conference of the Transportation Planning and Implementation Methodologies for Developing Countries (TPMDC). It covers the broad area of transportation planning and policy, pavement design and engineering, emerging technologies in transportation, traffic management, operations, and safety, and sustainable mobility in transportation. The book aims to provide deeper understanding of the transportation issues, solutions, and learnings from the implemented solutions. This book will be of best interest for academicians, researchers, policy makers, and practitioners.

This book presents the select proceedings of the 2nd International Conference on Transportation Infrastructure Projects: Conception to Execution (TIPCE 2022) and emphasizes the understanding of transportation infrastructure projects being conceptualized, designed, and executed so as to bring the desired development in the focused area. It comprises case studies from the transportation sector, construction industries, consulting agencies, and academia. These studies present the bottlenecks experienced during the implementation of the projects, from their conceptualization to their execution and the corrective measures that were incorporated to finish the work. The book will be a valuable reference for beginners, researchers, and professionals interested in construction planning and technology, infrastructure engineering, highway engineering, traffic and transportation planning and systems.

This book (in three volumes) comprises the proceedings of the Fifth Conference of Transportation Research Group of India (CTRG2019) focusing on emerging opportunities and challenges in the field of transportation of people and freight. The contents of the book include characterization of conventional and innovative pavement materials, operational effects of road geometry, user impact of multimodal transport projects, spatial analysis of travel patterns, socio-economic impacts of transport projects, analysis of transportation policy and planning for safety and security, technology-enabled models of mobility services, etc. This book will be beneficial to researchers, educators, practitioners and policymakers alike.

One of the key aspects of industrial machines, devices, and processes is heat transfer to maintain their functionality and achievements for better product quality. Therefore, various types of heat exchangers are involved to remove heat and maintain desired operating temperatures. However, to determine the requirement of space the size of a heat exchanger is matters (i.e. dimensions) of the machine/device or plant treatment. The objective of this study is to design theoretically analyze, then optimize performance using CFD. The theoretical study using the LMTD method for concurrent heat exchange is done, while the pressure drops and energy consumption are calculated using the Kern method. In this study, CFD ANAYALSIS THREE CASES analyzed the behavior of heat transfer, mass flow rates, pressure drops, flow rates, and eddies of tube bundle currents in the heat exchanger. The theoretically and CFD-based analysis is shown on only 1.15% in terms of hot fluid cooling performance. Overall, the results of this study confirm that CFD modeling can hold promise for heat exchanger design and optimization, allowing you to test many design options without building physical prototypes.
