The prompt
Create a 3D CAD model of a compact annular heat exchanger for CFD simulation. **Inner reactor:** - AISI 304 stainless steel. - Outer diameter: 88.9 mm. - Wall thickness: 3.05 mm. - Cylindrical length: 90 mm. - Two rounded 3-inch pipe end caps. **Outer housing:** - Cylindrical shell, concentric with the reactor. - Internal diameter: 105 mm. - Length: 130 mm. - Reactor centered inside, creating an approximately 8.05 mm radial annular gap. - Closed ends with gas inlet and outlet connections. **Gas flow:** Exhaust gas enters one end, flows through the annular space around the reactor, and exits at the opposite end. **Important:** - No baffles, fins, or internal obstacles. - Keep the reactor, outer housing, and gas-flow volume as separate bodies. - Ensure the gas-flow volume is continuous from inlet to outlet. - Make the geometry suitable for CFD and conjugate heat transfer simulation. Do not change the specified dimensions.
