Hello Everyone,

I am simulating forced convective nanofluid flow over a circular cylinder. The flow is steady laminar and 2D. Reynolds is 40.

In general, with increase in particle volume fraction; the drag coefficient will increase. But, I am observing a decrease in drag coefficient with increase in particle volume fraction.

FYI : I am getting reasonable values of Mean Nusselt number. Also, it increases with increase in volume fraction.

Pls help me solve this.

Thank You.

With Thanks,
