ABSTRACT The quest for an engine which having the same or more power with higher fuel efficiency than the existing ones has started before many years. As a result of all these researches a new engine concept is formed‚ which is a six stroke engine. Lot of research works are conducting on this topic nowadays and already six types of six stroke engines were discovered yet. Of these the resent developed three six stroke engines‚ i.e.‚ Beare head‚ Bruce crowers and Velozeta’s are undergoing

demonstrate the working principles of industrial heat exchangers ii. To investigate the efficiency of the heat exchanger in parallel and counter flow arrangements 1.0 INTRODUCTION A heat exchanger is equipment in which heat exchange takes place between 2 fluids that enter and exit at different temperatures. The main function of heat exchanger is to either remove heat from a hot fluid or to add heat to the cold fluid. The direction of fluid motion inside the heat exchanger can normally categorised as

Cross Flow Heat Exchanger Experiment By Andres Rodriguez Abstract The design project of the group was to create an experiment for Thermo/Fluids Laboratory. The experiment will help aide the students in relating pressure drop and heat transfer in a cross flow heat exchanger. The experiment consists of three cross flow heat exchangers (bare inline‚ bare staggered‚ and finned staggered) that will cool hot water with current fan in the Laboratory. Optimal flow rates‚ pressure and temperature

UNSTEADY STATE HEAT TRANSFER Heat transfer processes are prominent in engineering due to several applications in industry and environment. Heat transfer is central to the performance of propulsion systems‚ design of conventional space and water heating systems‚ cooling of electronic equipment‚ and many manufacturing processes (Campos 3). Unsteady state conduction is the class of heat transfer in which the temperature of the conducting medium varies with time and position. This occurs frequently in

conducted was to analyse the work of a heat exchanger‚ by studying the effects of heat transfer from a hot stream and a cold stream in the heat exchanger. In the experiment we were introduced to the shell and tube heat exchanger and were told of all its parts and how to use them. The experiment started by evaluating what the heat transfer rate for a hot stream and a cold stream was within the heat exchanger. Using this information the experiment went on to analyse the heat exchanger in more detail. The log
