Doubletube heat exchanger Download Scientific Diagram
Double Pipe Heat Exchangers- Heat exchangers are devices that transfer or exchange heat between two fluids without mixing and include various types depending on the design, application, required space, and the fluid flows in the system. All the heat exchangers have a barrier that separates the fluids and allows the heat transfer simultaneously.
Heat Exchangers Introduction Flow Arrangements and Types
A double-pipe heat exchanger is the simplest type of heat exchanger and can operate with co-current (Figure 1) or counter-current (Figure 2) flow. The design consists of a single small pipe (tube-side) inside of a larger one (shell-side). A co-current heat exchanger is most commonly used when you want the exiting streams to leave the exchanger.

Double Pipe Heat Exchangers Layout. As shown below, the double pipe heat exchanger consists of a pipe within a pipe. Both pipes have a return bend at one end. Double Pipe Heat Exchanger Construction. The inner pipe is fitted with fins. The outer pipe acts as shell. The shell nozzles are mounted vertically from the outer pipe, and the tube.
Double Pipe Heat Exchanger Pharmacy Scope
A double pipe heat exchanger is a heat exchanger that uses two pipes to exchange heat between two fluids. One pipe has hot fluid while the other pipe has cold fluid. This heat exchanger is also called a jacketed U-tube, jacketed tube, hairpin, and pipe-in-pipe heat exchanger. They are most commonly used for transporting heat and air.

This study numerically investigates a double pipe heat exchanger with triangle and rectangle rib. The simulation is performed using ANSYS package, considering turbulent flow and k-e turbulence.
What is Double Pipe Heat Exchanger Types. Working Principles Linquip (2022)
For first iteration a Length of double pipe exchanger is assumed and heat transfer coefficient is calculated. Viscosity correction factor (μ / μ w) 0.14 due to wall temperature is considered 1. For Laminar Flow (Re <= 2300), Seider Tate equation is used. Nu = 1.86 (Re.Pr.De/L )1/3(μ/ μw)0.14. For Transient & Turbulent Flow (Re > 2300.
What is a Double Tube Heat Exchanger? Zwirner Equipment Company
A double pipe exchanger is suited for "dirty" service because it is easy to dismantle and clean. In addition, a pipe exchanger can be considered in the following situations: 1. When the shell side coefficient is less than half that of the tube side; the annular side coefficient can be made comparable to the tube side. 2.
