Mixture properties and fluid phase equilibria calculations |
|
Simulis Thermodynamics is a thermophysical properties calculation server available as an MS-Excel add-in, a MATLAB toolbox or as a module pluggable in any other software that requires quality thermophysical properties.
Objectives
Simulis Thermodynamics provides engineers and software developers with an accurate and reliable thermophysical properties calculation server. These calculations can be integrated in any package intended for wider fields of application (equipment sizing, system modeling, etc) in order to ensure the consistency and reliability the data used and of the results.
| Simulis Thermodynamics is designed to |
 |
Provide access to over 300 functions, in particular for calculation of any type of transport properties (specific heat, viscosity,...), of thermodynamic properties (enthalpy, compressibility factor,...) or of phase equilibria (VLE, LLE, VLLE, salt formation,...) on multi components mixtures |
|
Provide access to one of the richest thermodynamic models libraries available on the market (equation of state, activity coefficients...) |
|
Provide access to a property database of 1920 pure components |
|
Enable the engineer to focus on his application and to works with thermophysical properties calculations that are reliable, and validated through intensive usage in industrial applications |
| In support of your thermodynamic expertise, Simulis Thermodynamics will enable you to: |
|
Adjust the best thermodynamic representation of your system. |
|
Perpetuate your expertise with easily created "Property Packages" that include all elements needed for further calculations (pure components properties, models, interaction coefficients,...) |
|
Dispatch these "Property Packages" throughout your organization in order for them to be used in your usual, CAPE-OPEN compliant, software. |
|

Simulis Thermodynamics:
Providing powerful calculation at reduced price
If the price of the Simulis Thermodynamics license is well below that of similar products available on the market, it is because, from the launch of the Simulis components suite, ProSim made the strategic decision to follow a new business model in which profitability is based on reduced prices and large volumes.
License prices could be significantly reduced as efficiency gains, acquired through uncommon technological choices, are transferred to the customers. In particular, these technological choices have their full effect at:
| - | the development level, the main element of the software cost, the "component" based technology of Simulis, allows the re-use of existing codes to a large extent and thereby minimises development and validation costs; |
| - | the distribution level, the other major software cost element, the choice of the online internet sales as the main channel allows substantial commercial expenses reduction. |
A large volume is expected as studies show that, in the same company, thermodynamic calculations can be performed by many engineers and technicians and not only by process simulation and modelling specialists. These calculations only need to be accessible in a familiar working environment such as MS-Excel for example. Furthermore, numerous fields of engineering sciences, beside process engineering, also require quality thermophysical properties. It is the case of heat transfer for example, but also aerodynamics, physics, hydraulics, mechanical, material, etc.
Thanks to its ability to be integrated in third party packages, Simulis Thermodynamics can be embedded in software designed for wider fields of application such as CFD, equipment design (heat exchangers, compressors, pipe-lines, etc.) or model based control tools . In this case, run-time licenses are proposed and the distribution is ensured by the developer himself (please consult).
The price of the Simulis Thermodynamics license is not explained by a lower quality of the software. Nor is this software a reduced version of a more complete product. It actually includes the complete component databases and thermodynamic models that are available in other ProSim software. It was not developed by unqualified engineers, but is the result of more than fifteen years of activity in the field and continues to be enriched by thermodynamic experts. The price of license you benefit from is only linked to the business model chosen.

Easy integration in your applications
Simulis Thermodynamics component-oriented architecture allows an easy integration in any COM/DCOM technology compliant application. This includes in particular MS Excel, MATLAB, C++, Delphi, etc.
Calls to the routines can be automated through the simple adjustment of the API in languages such as Visual Basic C++, FORTRAN, etc...
CAPE-OPEN standard compliance
Simulis Thermodynamics integrates the standardised CAPE-OPEN interfaces ("Thermodynamic plug" and "Thermodynamic socket"). It generates "Property Packages" that can be used with other simulation applications that are CAPE-OPEN compliant. Furthermore, you can use third party thermodynamic packages in Simulis Thermodynamics.
[ See current status of CAPE-OPEN compatibility ]
|
Thermodynamic plug: provides the ability to generate CAPE-OPEN "Property Packages" that can be used with compliant applications (calculates all properties and phase equilibria available in Simulis Thermodynamics)
|
|
Thermodynamic socket: provides the ability to use a property package generated by a third party application.
 |
Any application that integrates Simulis Thermodynamics automatically benefits from its CAPE-OPEN compliance.
Calculation features
Simulis Thermodynamics, allows the engineer to calculate properties and phases equilibria on single component systems or on systems that include up to 200 chemical components.
|
Thermodynamic properties calculations: transport properties, enthalpy, entropy, compressibility properties, non-ideality properties... |
|
Phases equilibria calculations: liquid-vapor, liquid-liquid, liquid-liquid-vapor equilibrium (bubble and dew temperatures, bubble and dew pressures, flash at given enthalpy, phase envelope, etc...) |
|
Regression calculations: functions for the fitting of experimental pure component properties, depending on temperature |
|
An extensive thermodynamic models library: Soave-Redlich-Kwong, Peng-Robinson, Lee-Kesler-Plöcker, NRTL, UNIFAC etc... These models were selected for their reliability and efficiency |
|
A database of 1920 components: developed from the DIPPR database and enriched with data from research projects and studies conducted by ProSim's thermodynamic experts. Furthermore, the last release of AIChE's DIPPR® database can be added (optional). |
|
Integration and flexibility: the ability to integrate your own "private" component databases or thermodynamic models |
|
Many additional services: graphical visualization of the different properties on temperature, pressure or composition ranges, property tables generation, experimental properties regressions, pure components properties estimations, phase envelope diagram plotting, petroleum cut properties generation, calculation of derivative value of pure substance properties with respect to temperature, pressure and composition, ternary diagram plotting...
