Shell and Tube Heat Exchanger Design software (S&THex). Very easy to use and user friendly.
S&THex is a software tool that is made to demonstrate the chemical design & rating calculations of Shell & Tube Heat Exchangers. Unlike other tools, ensures that the calculations are performed step by step to help in understanding the design calculations.
Please note that the software can only do the basic chemical design & rating calculations of shell and tube heat exchangers and some mechanical design calculations.
Shell and Tube heat exchanger design Software Features
- Step by step design and rating calculations.
- Support S.I Units and English (U.S) Units of measurement
- Rating and Design Modes
- Units converter containing 23 measurements and 200 units conversions
- Save, Load and generate result in different formats
- Compare unlimited cases in data grid table
- Add your own Nusselt number correlation to be used in the design mode or rating mode. The correlation can be added in the following format;
Nusselt number = C * [Reynolds number ^ a] * [Prandtl number ^ b] * [Viscosity term ^ c]
Where; C, a, b and c are input variable defined by the user. the user can also choose to omit the viscosity term if needed.
Results:
- Generate Results and export it to Shell & Tube Engineering Data sheet that can be also saved as a .pdf document.
- Export results to Microsoft excel generated data sheet for editing.
- Export Results summary to .csv file format that can be opened in Microsoft Excel
- Export Results summary to .rtf file format that can be opened in Microsoft Word
- Print preview / print Results summary
Calculations:
- Unknown Flow rate on either shell or tube side
- Unknown temperature on shell side or tube side
- Unknown exit temperatures on both sides
- Duty, Area, Shell and Tube velocities
- Number of Baffles and Baffle spacing, Number of tubes, Scale resistance (dirt factor)
- Overall heat transfer coefficient for both Clean, Fouled and Required conditions
- Select from different correlations to calculate shell or tube heat transfer coefficient
- Shell/Tube side Reynolds & Nusselt numbers
