Coordinate Dependent Ambient Temperature

Dear friends and fluent experts.
I want to simulate thermal stratification in the problem of buoyant jet. A buoyant jet enters from a slit into ambient with thermal stratification, that is ambient temperature varying with x coordinate. I've posted Momentum equation of the problem. Also you can see boundary conditions for buoyant jet. As you can see in the momentum Eq. the term related to boussinesq approximation is t(infinity,x) instead of a constant temperature. I've tried
(DEFINE_INIT) UDF code but I don't get any stratification in steady state solution.
Can anyone please help me?
