Hello everyone,

I am trying to simulate slug flow pattern using a T junction(6mm in diameter, made of quartz glass) with Water and Toluene. I have added input conditions as per a research paper but instead of toluene in slug, I am getting water as slugs in toluene.

I have taken wetted wall condition with slip length = h (average element size) and contact angle = 34 degrees.

I have attached my model. The image attached show fluid 2 (Toluene) as continuous phase and Water as slugs. It should be the inverse.

Please help me understand situation and correct the problem.

Thanks
