Shell-and-tube heat exchangers can have multiple passes, such as 1-1, 1-2, 1-4, 1-6, and 1-8 exchangers, where the first number denotes the number of the shells and the second number denotes the number of passes.
All About Shell And Tube Heat Exchangers - What You Need Shell and tube heat exchangers can be single-phase, or two-phase. A single-phase exchanger keeps the fluids phase constant throughout the process (e.g. liquid water enters, liquid water leaves) while a two-phase exchanger will cause a phase change during heat transfer process (e.g. steam enters and liquid water leaves).
Shell and tube heat exchangers are constructed of a single tube or series of parallel tubes (i.e., tube bundle) enclosed within a sealed, cylindrical pressure vessel (i.e., shell). One fluid flows through the smaller tube or tubes, and the other fluid flows around the

A shell and tube heat exchanger consists of a bundle of tubes enclosed in a cylindrical shell. The ends of the tubes are fitted into tube sheets, which separate the primary and the secondary fluids.
Process Design of Heat Exchanger:Types of Heat Thermal design of a shell and tube heat exchanger typically includes the determination of heat transfer area, number of tubes, tube length and diameter, tube layout, number of shell and tube passes, type of heat exchanger (fixed tube sheet, removable tube bundle
I am working on checking the design for a shell and tube heat Exchanger. We have 4 shell and tube heat exchangers to cool the quench tank water from 160 deg f to 120 deg f using two water chiller connected to 1st & 2nd as well as 3rd & 4th heat exchanger. The temperature of cold water is 80 deg f. The pump flow rate for hot water is 375GPM
Shell & Tube Heat Exchanger Design You Are Asked T Shell & Tube Heat Exchanger Design You are asked to design a condenser than consists of a shell and tube heat exchanger having a single shell with multiple tube passes. The condenser is to be used in a Rankine cycle to condense high quality steam into saturated water (at 46 °C). Cooling water enters the condenser at 15 °C and exits at 25 °C.
Shell & tube heat exchanger diagram - EnggCyclopediaMay 13, 2019 · Shell & tube heat exchangers This type of heat exchangers consists of metal tubes passing through another metal enclosure, which is referred to as the 'shell'. So typically we have a fluid on shell side and anther fluid on the tube side. Heat transfer
Heat Exchanger ThermodynamicsBasic Principles Underlying Heat ExchangersHeat Exchanger Design CharacteristicsTypes of Heat ExchangersHeat Exchanger Selection ConsiderationsApplications of Heat ExchangersSummaryThe design of a heat exchanger is an exercise in thermodynamics, which is the science that deals with heat energy flow, temperature, and the relationships to other forms of energy. To understand heat exchanger thermodynamics, a good starting point is to learn about the three ways in which heat can be transferred conduction, convection, and radiation. In the sections below, a review of each of these heat transfer modes is presented.Good Practice For Heat Exchanger Selection And Design.LMTD formula assumes pure countercurrent flow. Ft is correction factor, on LMTD for co-current and cross-flow heat exchangers. Ft is one for pure countercurrent flow. Minimum value of Ft should be between 0.9 and 0.95. Ft is a measure of heat transfer efficiency and temperature cross. A low value of Ft indicates reverse heat flow in some part E1-MNL032A - Design and Rating of Shell and Tube Heat The optimum thermal design of a shell and tube heat exchanger involves the consideration of many interacting design parameters which can be summarised as follows:Process 1. Process fluid assignments to shell side or tube side. 2. Selection of stream temperature specifications. 3. Setting shell side and tube side pressure drop design limits. 4.
