Can’t Share Heat with Pipe (G)
Hi,
I am in intership and I would like in Simscape to simulate an air duct heated by a heat source. For this, a started with a block Pipe (G) with a lenght of 5m, an area of 0.5 m^2 and I used the formula for the hydraulic diametre D_h=4A/P. Then I put a block Reservoir (G) on both side of the pipe with an ambiant temperature (25°C) and 1 atm and I put also a flow source with a volumetric flow of 5 m^3/s.
On the port H, I started with a temperature source (40°C) and a convective block with an area of 1.7 m^2 and a heat transfert coefficient of 20 W/(m^2.K).
When I launch my simulation, the temperature of the air remain at 25°C and the temperature of the thermal part drop to 26.7°C. I have a heat flow of 452.6 W from thermal part to gas part so the air have to be heated but it’s not the case.
Can you please help me ? Thank you !Hi,
