CONVAL® 7.0.4 SP1 available
The CONVAL 7.0.4 Service Pack 1 fixes the following issues:
Safety relief valves
With calculations according to EN ISO 4126-1 the permitted discharge coefficient Kdr is incorrectly multiplied again by 0,9. That results in a too largely computed required flow cross-section A0.
Property calculation
The substance R 134a is not thermodynamically computed, although it is intended for it.
This problem concerns only CONVAL versions including the extended property calculation package.
Control valve - two phases
The operating density at the valve outlet of the liquid phase with flashing fluids is not always computed.
Thermodynamically computed fluids and water are not concerned.
Tank depressurization
In certain cases the simulation breaks with a protection error.
The service release can be downloaded free of charge.
