Brownian dynamic simulation for the prediction of effective thermal conductivity of nanofluid

摘要: Nanofluid is a colloidal solution of nanosized solid particles in liquids. Nanofluids show anomalously high thermal conductivity comparison to the base fluid, fact that has drawn interest lots research groups. Thermal nanofluids depends on factors such as nature fluid and nanoparticle, particle concentration, temperature size particles. Also, significant change properties viscosity specific heat fluid. Hence, theoretical model becomes important order optimize nanofluid dispersion (with respect size, volume fraction, temperature, etc.) for its performance. As molecular dynamic simulation computationally expensive, here technique Brownian coupled with Green Kubo been used compute nanofluids. The simulations were performed different concentration ranging from 0.5 3 vol%, 15 150 nm 290 320 K. results compared available experimental data, they found be close agreement. also brings light physical aspect like role motion enhancement
