The fabrication, of the TAG, has had to be considered to be performed at ETL (due to the expertise there). Therefore, materials have gradually been sourced and ordered as the relevant information has been made available. Some pre-subcontracting has inevitably occurred, with some outsourcing (during the fabrication) necessary due to the lack of specific experience in those fields.
Thermo-fluid and then mechanical-stress analyses have been in progress (for only the HHX i.e. Hot Heat Exchanger). An achievement (during the thermo-fluid work) is that the HHX effectiveness / efficiency was very close to the originally predicted 30% (at 29%). Clearly, these could affect the model so that eventually a final design could be optimised.
Accounting for this the fabrication, of the TAG, has had to be considered to be performed at ETL (due to the expertise there).
Technical deliverables had been written (by ETL), and TA analysis had been undertaken (by UoL). This has led to a preliminary TAG (or Thermo-Acoustic Generator) design model being devised based on the schematic below. TWI were just starting the thermal-stress analysis, and the other task of joining methodologies.
The progress up until this point was that ETL (the project leader) had initiated communication with the other two members (UoL and TWI). An intermediate meeting was arranged, during this quarter, as the first “ face-to-face “ overall technical discussion with UoL (since the project began). UoL presented a type of TA design plan, and this was discussed. Individually, each member had their roles: ETL co-ordinating their work and the work of others, and understanding TA technicalities; UoL deciding on a design plan; and TWI being informed regarding the developments (their role being due for Q3).
