This App helps to evaluate performance in a shell and tube heat exchanger in terms of its over all heat transfer U-coefficient. It also helps to determine different maintenance requirements like cleaning schedule based on changes in its performance characteristics due to degradation.

Manufacturers generally provide design specification data such as heat transfer Area, U-coefficient, effectiveness for a given capacity performance. However, these values tend to vary over a period of time and often it is necessary to evaluate and compare design specification data with actual performance. This app serves as a tool for different maintenance personnel, energy and application engineers in monitoring performance and energy efficiency in a shell and tube heat exchanger.

Fluid Properties:
Users can quickly select different fluids for both shell side and tube side application from a list of most common fluids used in industrial applications. The key property data such as density and heat capacity is evaluated based on given temperature and pressure for the given fluid. For fluids that are not in the list, users can create a custom fluid with known property data. Data can be edited in both SI and USCS unit standards.

Heat Exchanger Data:
One can choose heat exchanger design depending upon type of application as well as flow pattern with in shell and tube fluids such as counter, parallel and cross flows. Both inside and outside heat transfer area can be computed using the tube side dimensional data as shown in the screen shots. Hence U-coefficient can be determined accordingly.

Performance Summary
The over all heat transfer coefficient is computed and presented in the main screen. The performance summary is provided on a separate screen as shown in the screen shot. Application notes has all the definition and brief descriptions of various computation model used to determine different key parameters presented in the summary.
