Multiphase flow of nanofluids - Low Nusselt number problem

Am Aarthy, I am new to FLUENT.
I am modelling 2-D flow and heat transfer of nanofluids around an unconfined square cylinder for my M.Tech project. Initially, I tried a single phase flow using effective property models for properties of nanofluids. Those simualtions are fine and gave comparable results with the literature.
Now, I am trying to use multi-phase flow model. I am trying with mixture model in FLUENT. I tried with particle volume fraction as 0 (i.e., pure basefluid), and I got good values of Nu and drag coefficients which matched with literature.
When I increased the particle volume fraction, the values of Nu and C_D decreased. But, it is well known that, when particle volume fraction is increased, C_D and Nu will increase.
So I am stuck with this. Kindly, pls help me very urgent....
