In one of my designs I have a need for a material that simulates Ceramic Insulation.
Seen here:
My design is a cooking device that uses wood for combustion inside the Burn Chamber Channels as well as Propane Gas when it is preferred or required.
Wood in this device can burn up to 1200 degree Celsius under the right circumstances because of the unique innovative design that creates a high air flow through the combusting wood. It has been tested with an actual prototype built out of bricks. Many call it a the common name of a 'Rocket Stove' but this new design is much more than a simple brick fireplace that requires a lot of maintenance to operate.
It's called the Forge 2 and it can be seen here:
Here you see the device in all of its parts disassembled:
This image gets more to the point. As you can see in this image the Combustion Chamber section is intentionally taken apart so that one can view inside the design as you will notice it is hollow and that white material you see inside the hollow spaces is representative of High Temperature Heat Resistant Material such as 1 inch thick Ceramic Blanket. Seen here:
I've been learning how to run simulations with the 'Simulation' Workspace Environment within Fusion 360. When I ran the simulation without any insulation inside the left Combustion Chambers hollow space the heat of 600 degrees Celsius radiated outwards to the rest of the design quite effectively causing the lowest temperature to be around 120 degrees Celsius located at the Silicone Handles that extend out of each left and right side of the first level section and the majority of the steel was at the range of 350 degrees Celsius or higher.
I presume that by adding a High Temperature Resistant Insulation to the internal hollow space of the combustion chambers would prevent the heat inside the left and/or right Combustion Chamber Channels from effectively making its way to the exterior components that make up each of the 5 sections on the device.
I am running simulations because I am intending to make sure that the exterior components of the device such as the handles and exterior body panel do not exceed temperatures beyond that which can cause burns to skin. Ideally the High Temperature Insulation Material would enable this ability of the devices exterior components to stay cool. However, as we all know, barbecues and other cooking devices operate at temperatures easily high enough to cause burns or damage to material. Therefore, it isn't mandatory that this device be able to keep its exteriors cool but it is definitely preferred.
Now, if Fusion 360 had a High Temperature Insulating Material that was configured to have realistic effects according the specifications of these real types of materials then Fusion 360 users could simulate tests on a lot of model variations that deal with fire and heat like my Forge 2 device.
I ran the simulation with Rubber, Silicone inside the hollow space of the level 1 combustion chamber at 600 degrees Celsius as I previous performed without the Silicone and I'm not quite sure if the results were much different between the two. It seems it will require further investigation to figure out if materials have any kind of insulating effects as a ceramic fiber type of material does for keeping heat inside something or blocking it from getting somewhere.
If anyone knows about insulation effects of materials in respect to running simulations having to do with temperature related loads it would be interesting to hear.
In fact, I think I am going to google that inquiry right now.
