Simple yet Effective -
Proportional Heater
Sinda/Fluint 3.3 includes enhancements like a proportional heater
routine that easily maintains temperatures of critical components.
Here's how it works along with some results:
In this example, we want to maintain the temperature of node MAIN.3
between 20 and 30 C. Node 3 is connected to two other nodes, a boundary
node MAIN.1 with a temperature of -200 C and an additional diffusion
node MAIN.2 with an initial temperture the same as MAIN.3 of 50 C.
Proportional heating is applied to MAIN.3 when the temperature drops to
20 C. The heater is said to be proportional because heating of 100 to 10
W is applied proportionally between 20 C and 30 C.
