Support Which Allow Thermal Stress

Hi,

aluminum at 500°C??? why that? What is inside so you need Al? Which alloy?

Any fluid I know will either react with the aluminum (water) or decompose (hydrocarbons or silanes) or alloy (metals).

Transmission of load is here more precise transmission of pressure.

Let a fluid in the gap be pressurised to the same pressure as the inside.

Give some more details!

This is not a device to play with.

You can easily do a lot of damage to yourself and others!

thanks for your answer..yes i know it's somewhat dangerous.thats why i'm searching for a perfect design.actually i need a space to allow air with minimum flow resistant in between the two spheres. the inner sphere and then a outer hollow sphere in between these two some space must be there to allow free flow of fluid. the outer sphere acts as a cover,. u can imagine a combustion similar to IC engines takes place inside the inner sphere.thanks in advance.click the following link. http://www.scribd.com/doc/36002470/rigidly-support-a-body-with-thermal-expansion
