SUMMARY

The BMW turbosteamer concept utilizes waste heat from exhaust gases to generate steam, which powers a turbine connected directly to the crankshaft. The system faces challenges in ensuring only steam enters the turbine, likely employing a liquid trap to prevent liquid phase ingestion. Additionally, the variability in turbine speed presents difficulties in synchronization with the crankshaft, suggesting the potential use of a continuously variable transmission (CVT) for effective power transfer. The system's efficiency is contingent on maintaining high pressure and temperature, with concerns regarding water supply and leakage management.

PREREQUISITES
  • Understanding of thermodynamics and heat transfer principles
  • Familiarity with steam turbine mechanics
  • Knowledge of continuously variable transmission (CVT) systems
  • Experience with plumbing and fluid dynamics in high-pressure systems
NEXT STEPS
  • Research the design and operation of waste heat recovery systems
  • Study the principles of steam turbine efficiency and performance
  • Explore the application of continuously variable transmissions in automotive engineering
  • Investigate methods for managing fluid distribution in heat exchangers
USEFUL FOR

Automotive engineers, mechanical engineers, and researchers interested in waste heat recovery and steam turbine technology will benefit from this discussion.

plus it's a bit difficult to place the hex vertical on the exhaust pipe of the care don't u think ?

having the exhaust on tube side means huge pressure drop which means a back pressure.
What's the pressure loss from pushing the exhaust through the shell side of your tube bundle? That's not a free ride either. By the way, how much backpressure is acceptable? I think you need to know that before you can decide what your boiler should look like.

ur sure it wil work ?

No, but it's not my project. I'm just throwing ideas at you.

PS: You should get into the habit of typing out real words. Once you're out of school nobody wants to read text-speak.
