The software will do all the thermal calculations involved in the design and will generate a summary of all results.
Below is a list of some functions:
Double pipe heat exchanger design (DHex) software features:
- Support S.I Units and English (U.S) Units of measurement.
- Units converter includes 23 measurements units with 200-unit conversion
- Ability to import properties to Hot/Cold sides from Microsoft Excel.
- Add your own Nusselt correlation
- Save/Load results
- Ability to calculate unknown Cold or Hot side temperatures. Unknown exit temperatures on both sides or any two temperatures on both sides
- Unknown Flow rate on either hot or cold side
- Perform thermal analysis for bare tube double pipe (hairpin) heat exchangers.
- Perform thermal analysis for finned tube double pipe (hairpin) heat exchangers.
- Choose from Counter Current or Co-Current Flow arrangement
- Choose from Series arrangement or Series-Parallel arrangement.
- The software will also tell you the location of Hot/Cold fluids within the heat exchanger (Inner Pipe or Outer Pipe).
- Select from different correlations to calculate Cold/Hot side heat transfer coefficient. Also, the ability to adjust Nusselt number if you do have a different correlation.
- Calculate the Area, Flow area, Length, Log Mean Temperature Difference, Number of Hairpins, Unknown Flow rate.
- Calculate the scale resistance (dirt factor), Equivalent Diameter.
- Calculate Inner Pipe/Outer Pipe (Annulus) side Reynolds, Nusselt numbers & Prandtl Numbers.
- Duty Calculation, Clean and Design Overall heat transfer coefficient calculations
- The ability to define the Duty also the ability to define the heat transfer coefficient on either side.
- Inner Pipe/Outer Pipe (Annulus) velocities and Mass velocity calculations
- Number of Transfer Units and Thermal Capacity ratio calculation.
- Clean and Fouled Fin Efficiency calculations for finned tube heat exchanger.
- Pressure drop calculations & Entrance and Exit losses.
- Pumping power calculation.
- Plot Temperature profile for hot and cold sides. This aids in also identifying any temperature cross.
- Estimate the Physical properties of pure components for more than 1450 fluids; the database has the ability to estimate Thermal Conductivity, Density, Heat Capacity and Viscosity. The database also included critical properties, boiling and melting points and come as a standalone interface but easily integrated with the software.
- Estimate mixture properties. (ALL ESTIMATION METHODS CURRENTLY SUPPORT LIQUIDS ONLY)
- User database functions to allow user to add/delete fluids, pipe sizes and heat transfer coefficients and load to hot/cold side (Empty database!).
- Fouling factors
- Export Results summary to Microsoft Excel Engineering Datasheet format. Save/Load results. Generate/Print a summary of results
- Display multiple cases in results grid
- Export Results summary to .rtf file format that can be opened in Microsoft Word
- Single phase fluid operations with exception to steam which is supported.
- Single tube units, multi tubes are not supported.
