Sharma, B., Kumar, S., & Paswan, M. K. (2019). Numerical investigation of MHD stagnation-point flow and heat transfer of sodium alginate non-Newtonian nanofluid. Nonlinear Engineering, 8(1), 179-192. in this paper, you have to include table of thermophysical properties of different nanoparticle cu, TIo, SA. you also share for the thermal expansion parameter beta of sodium alginate fluid have presented different value like as 0.99, by Ilyas khan 99 by and 23 by what is reason behind it why they are different for same fluid
