Heat Exchanger Corrosion & Failure - Shell and Tube Heat ...Fluid velocity in excess of the manufacturer recommendation on either the shell or tube side of the heat exchanger will likely cause erosion damage as metal wears from the tubing surfaces. If any corrosion is already present on the exchanger, the erosion is accelerated, exposing the underlying metal to further attack without a protective coating.

Heat Exchanger Fluid Velocity – Why Should I Care?Often less understood, is the effect of velocity on the thermal transfer characteristics of the heat exchanger: It turns out that the higher the velocity through the heat exchanger, the higher the turbulence — and the higher the turbulence, the more efficient the thermal transfer. You may be wondering how that can be.
5.1 Shell-and-Tube Heat Exchangers - Homepages at WMUShell-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. An odd number of tube passes is seldom used except the 1-1 exchanger. A 1-2 shell-and-tube heat exchanger is illustrated in Figure 5.19.

Heat Exchanger Theory and the Heat Exchanger Design EquationHeat transfer theory tells us that the log mean temperature difference is the average temperature difference to use in heat exchanger design equation calculations. The basic heat exchanger design equation can be used for a variety of types of heat exchangers, like double pipe heat exchangers or shell and tube heat exchangers.
Heat Exchangers Classification, governing Equations and ...4. Shell and Tube Heat Exchangers. The shell-and-tube heat exchanger is the most common style found in industry. A shell-and-tube heat exchanger has a cylindrical shell that surrounds a tube bundle. Fluid flow through the exchanger is referred to as tubeside flow or shell-side flow.

Shell and Tube Heat Exchangers: CalculationsShell and Tube Heat Exchangers: Calculations. The basic design calculation for any heat exchanger is the determination of heat transfer area. Most generally, this is done using although in practice it is more common to assume that fluid properties can be treated as constant at the bulk average values, and approximate the design equation with:
Maximum Velocities in Heat Exchangers – Part 1Maximum Velocities in Heat Exchangers . Let's start by reviewing the recommended velocities in shell and tube heat exchangers in an HVAC heating application. The maximum velocity in the tubes is a function of several factors, including the tube material, the opening sizes, and the liquid type.
Shell & Tube Heat Exchangers - Thermal Systems§Tube side velocity for water and similar liquids ranges from 0.9 to 2.4 m/s (3 to 8 ft/sec) §Shell-side velocity from 0.6 to 1.5 m/s (2 to 5 ft/sec). q The lower velocity limit corresponds to limiting the fouling, and the upper velocity limit corresponds to limiting the rate of erosion.
VIBRATION IN HEAT EXCHANGERS - ThermopediaFlow separation from tube surfaces occurs where there is a transverse velocity component of the flow and mainly affects the vibration strength of the tubes in heat exchangers. The dynamic effect of the flow on a vibrating tube depends on the flow velocity and the vibration characteristics of the tube.
US4854373A - Heat exchanger for a pump motor - Google PatentsSince the tube 49 is connected to the high pressure side 18a of the centrifugal pump 18, water will be delivered through this tube 49 into the heat exchanger 30 and thence into the tube 50 and back to the low pressure side 18b of the heat exchanger 18 whenever the motor 20 and its pump 18 are operated.
