TransientGroup at SolarPACES 2017 in Santiago (Chile)

TransientGroup will be present at SolarPACES 2017 in Santiago, Chile from September 26 to 29.

Two articles will be presented by Matteo Losito, Sr. Process Engineer,  whose titles are:

  • Dynamic Analysis of Extraordinary Operations of MS Central Receiver (in collaboration with DLR, Germany)
  • 24h Dynamic Simulation of a CSP Solar Tower Demo Plant



Brochure ISAAC Dynamics

The new ISAAC Dynamics brochure can be now downloaded here


ID Connect

The new version of ISAAC Dynamics, ID 3.0, introduces the new tool ID Connect.

ID Connect allows users to connect ISAAC Dynamics with other software via TCP/IP communication protocol boosting ISAAC Dynamics capabilities beyond the platform limits. It will be also possible to split the calculation over many machines and speed up the process.


Demo models download

It is possible to download a set of demo models from here. The demos can be downloaded without any limitation and no activation is required.


TransientGroup in Rome at University of La Sapienza – for NESTER

TransientGroup presented the company and its activities in Rome – University of La Sapienza – during a 3 day workshop entitled “ENEA’s perspective on the development of Concentrating Solar Thermal Technologies”, together with other companies of CST context in Italy like ENEL, ENI, Archimede Solar Energy, ESE and others.

Real Gas Tables

TransientGroup has developed a new library in order to evaluate thermodynamic and transport properties of more than 100 real pure fluids, real gas mixtures and the most common refrigerant fluids. The new library is supplied with the following thermodynamic models: Peng-Robinson, NIST, GERG-04. It is possible to create graphs as well and interrogate the tables through a user-friendly interface.
