You are required to design a shell and tube heat exchanger having a rectangular cross section as shown in figure 1 below. The heat exchanger uses water as the cooling fluid to reduce the temperature of exhaust air from a natural gas furnace that is flowing through the tube. The target effectiveness is 48%. Figure 1: Geometry for Heat Exchanger The design constraints are as follows: Tube Side (Upper Channel) Input m = 0.01 kg/s Temperature 458.2K pressure 1.82 atm Output Shell Side (Lower Channel) Input m = 2.5 kg/s Temperature 292.2K = m=0.01kg/s pressure 1.0 atm Output m=2.5 kg/s pressure 1.0 atm Tube Shell Wall Thickness: 1.5 mm for both Shell and Tube Geometry: Must remain a Single Flow, Single Pass system in the stacked configuration shown in Figure 1. i.e. tube cannot be encapsulated with shell. Velocity U: Both shell and tube sides should a minimum value of at least 1.0 m/s and a maximum value between 2.5-3.0 m/s. Tube and Shell Dimensions: You may vary tube and shell dimensions (but the wall thickness must be constant). The height of either the tube or shell must not fall below 30 mm. Tube Length: minimum of 600 mm and a maximum of 1200 mm. Material: You may also vary the material of which the heat exchanger is made. Internal Profile: Additional geometries may be added to the tube and shell to enhance the effectiveness as needed. Manufacturability: The design must be manufacturable. Procedure: Using SolidWorks Flow Simulation, create a model of your design and determine the effectiveness of the heat exchanger.
