Pressure drop trend phyiscal not correct in t pipe
 
I am soving one problem using Fluent. Porblem descrption: There is a oil flow in T pipe. One inlet & 2 outlets. Both outlets are near to each other. I defined velocity inlet at inlet and pressure outlet at on e outlet and velocity inlet with -ve value at another outlet. I want to see the pressure drop for different flow distribution at outlet to calculate loss coefficients.I ran case with different flow distribution at outlet. When I look into results, pressure drop decreases with increasing flow rate at one outlet. I found there is high recirculation at actual outlet in both port. Actual outlet refer because of outlets are extended to avoid reverse flow. If somebody found the similar trends and know the reason why this is happen. Please share your vies with me.

Thanks in advance.
