F1 electric supercharge is using stored electricity at optimum times regardless of thermal efficiency in that mode ....saviour stivala wrote: โ06 Apr 2023, 05:09How can an exhaust turbine still be developing significant power in electric supercharging mode with waste-gate open and exhaust gasses by-passing the turbine?.
and ....
only in part do the exhaust gases bypass the turbine
only in part do their pulsations bypass the turbine
the pulses free power eg was used directly to increase aircraft speed - or indirectly via the recovery turbine & propeller
in the 'WGO effect'-by-design Wright the turbine recovery was higher than the compressor power
people (including USSR Zvezda 42 and 56 cylinder CI engine builders) built compound engines for a reason
