Sammendrag
The first part of this memo contains the information presented at the COPRO Consortium meeting 2018
with some additional information and results.
The models that was used in this analysis were developed and prepared as a task in HighEFF RA 2.1
The results from a screening of a tubes-in-shell heat exchanger compared to a novel plate-type design
for a given duty and desired maximum pressure loss indicated that for a plate type design a 90% core
weight- and 85% core volume reduction could be possible.
The investigated case was a heat recovery heat exchanger used in an indirect bottoming cycle for power
production for 150°C
The plate-type design will be followed up in HighEFF RA2.1 in cooperation with RA4 in 2019.
In the second part, experience on how derivative free optimisation framework NOMAD can be
implemented for process and heat exchanger optimisation are discussed. Comparison with gradient
based method in terms om time consumption and robustness are performed for a simple Rankine cycle.
