In this review paper , the effects of different parameters such as nanoparticle volume concentration , nanoparticle size , Reynolds number , temperature and tube flatting with nanofluids are discussed in detail. Numerical results show that theaddition of nanoparticle enhances the heat transfer and pressure loss of base fluid in all of the flat tubes at various Reynolds number and temperature .Both the relative average convective heat transfer coefficient and press drop can be enhanced by increasing nanoparticle volume concentration and decreasing nanoparticle size
