The first PRESLHY Review of Experimental Outcomes was organised on 26 June 2020, 14:30 – 16:30 CEST online via GotoMeeting https://global.gotomeeting.com/join/607285533
The focus was on the experiments done by partner HSE.
Agenda
1) Short motivation/intent of the experiments
2) Description of the set-up, sensors etc.
3) Experimental matrix
4) Results (measurement data, curves, correlations, videos including post-processing steps)
5) Discussion of exploitation – all (modelling, benchmarking, scientific publication,…..)

Documentation of the event
The documentation of the workshop is contained mainly in two presentations. The first presentation below provides details of the Rainout Experiments E3.5
The second presentation provided details on the Electrostatics Experiments E4.3 and the Rapid Phase Transition Experiments
The following discussion started about the E3.5 rainout experiments
Donatella Cirrone: How was T measurment done?
Answer by Jonathan Hall: TC3 surface contact type. Quality of signals is questionable.
Alexandros Venetsanos: Did the set-up account for massflux provided by the trailer?
Answer by Jonathan Hall: There is no mass flux measurement at the trailer.
Alexandros Venetsanos: What is the function of the heat exchanger inside the trailer tank?
Answer by Jonathan Hall: This is only to pressurise, not to provide gaseous H2
Satement by Jonathan Hall: Test started with warm release pipework
Satement by Jonathan Hall: Coriolis probe is not calibrated for T<-100°C
Alexandros Venetsanos: Why there is not Bernoulli based mass flux measurement?
Answer: How to use Bernoulli if not knowing density
Pratap Satiah: Was there measurement of H2 concentrations at ground level during the vent stack releases before the actual experiment?
Answer Simon Coldrick: This will be added to the report.
Stella Giannissi: Regarding the near field sensors, how much does the displacement contribute to the error in the signal?
Answer by Simon Coldrick: Unclear.
Alexandros Venetsanos: Are there T below 20K?
Answer by Jonathan Hall: It is assumed yes.
Stella Giannissi: Is the 5 bar 12mm the only case with LH2 release?
Answer by Simon Coldrick: Yes.
Stella Giannissi: Is the 5 bar 12mm the only case with LH2 release?
Answer by Simon Coldrick: Yes.
