Source term for decay -- CFD Online Discussion Forums

February 6, 2005, 13:43	Source term for decay	#1
Chimwemwe Guest Posts: n/a	CFD Users, I am trying to model bacteria decay based on first order kinetics. I want to use scalar to define this. The bacteria constant death rate is K/day. Bacteria decay at anytime= Inital bacteriaexp(-ktime) How can I set a source term of S=A+B*Bacteria (dependent variable) to reflet the decay at any point. Thanks in advance. Chimwemwe
