Concentric tube heat exchanger pdf. And we conducted experiment on parallel flow and counter flow of concentric tube heat exchanger for the determination of effectiveness of heat exchanger. Plot classic 4 point temperature profiles through the heat exchanger in Concurrent and Counter–Current flow. The document discusses the design and analysis of concentric tube heat exchangers, focusing on their function to transfer heat between two fluids in either co-current or counter-current flow configurations. Key findings included calculating the heat transferred, efficiency, log mean temperature difference, and determining the overall heat transfer The first type of a heat exchanger is called the recuperative type, in which heat are exchanged on either side of a dividing wall by fluids; The second type is regenerative type, in which hot and cold fluids are in the same space, which contain a matrix of materials that work alternately as source for heat flow. There are several criteria for heat exchangers classification: their geometry, the types of flow, the flow conditions, etc. Here we have made a concentric tube heat exchanger using the above specifications. Jun 4, 2021 · These are double-pipe or concentric tube heat exchangers, shell-and-tube heat exchangers, cross flow, and compact heat exchangers. . The transfer of heat from the hot fluid to the wall or tube surface is accomplished by convection, through the tube wall or plate by conduction, and then by convection to the cold fluid. This study as a whole offers an overview of an analytical method applicable to the design of concentric tube heat exchanger (counter-flow type) as shown schematically in the Appendix. The document describes an experiment conducted using a concentric tube heat exchanger to study heat transfer under co-current flow. This paper presents and discusses the flow and heat transfer performance of a parallel/ counter flow heat exchanger, when the heat transfer surface is provided with dimples on one or both sides (cold fluid side and hot fluid side). Thermodynamics Concentric Tube Heat Exchanger TD1360a Shows how a simple concentric shell and tube heat exchanger works. Heat transfer techniques are referring to different method used to increase rate of heat transfer without affecting much the overall performance of the system. To demonstrate the differences between counter-current flow (flows in opposing directions) and co-current flows (flows in the same direction) and the effect on heat transferred, temperature efficiencies and temperature profiles through a concentric tube heat exchanger. The objectives were to observe the temperature changes of the hot and cold fluids at the inlet, midpoint, and outlet. Introduction In this experiment, we will investigate the heat transfer performance of a concentric tube heat exchanger by measuring the temperatures and flow rates for different flow configurations. Mar 13, 2025 · Heat Exchanger Lab Page 1 of 9 Heat Exchanger Lab (MECH0004) 1. Investigate Logarithmic Mean Temperature difference, Overall Heat Transfer Coefficient and the Nusselt, Reynolds, Prandtl Relationship. Heat-exchanger design analysis method relates to size of the heat exchanger to the required heat-transfer ratings. Present study is to modify the inner tube of concentric tube heat exchanger with dimpled tube. Optional Computerised Data Acquisition Upgrade. Several studies on the passive techniques of heat transfer have reported in the past decade . Stabilises in minutes and allows rapid data collection. pvbjppxi vj gdlk uht4 bi1d ubyv ehdj pkpups uln63 n8
