Partition to reduce heat transfered with natural convection
Partition to reduce heat transfered with natural convection
(OP)
Hi all.
I have a problem where i have to find the best hight to put a partition so that i can reduce the air flow caused by natural convection inbetween two surfaces

It has something to do with the Rayleigh number , like i need to make it as small as possible. Also there is still heat transfered with conduction.
For example when the partition goes up the upper section has a smaller Rayleigh number but heat with conduction is transfered easier whereas the down section haw a higher Rayleigh number but heat with conduction is transfered more difficult because of the longer distance.
Any ideas woyld be really usefull
Thank you!!

Another option, if the top and bottom separation is small is to put layers of bubble wrap in the space.
