How set up to delta temp.

Postby changwoo.cho@gmail.com » Wed Feb 27, 2013 02:18

Hellow, everyone

I'm trying to simulate for thermal plume of power plant.
But I have no idea, how set up to increment of temperature (delta temp.)
(temperature of intake is 20 C--> temerature of outall is 20 C + delta temp.)
Could you explain to me how does this works
or post here your discharge file in similar case ?

Thanks a lot

Hi,

Here's a sample on how to do it. You need to define 2 discharges: the intake (negative flow) and the outfall (positive flow). The keywords are quite intuitive. Let me know if you have further questions.

Best regards,
Luis
