Versatility of nanouids made of nanoparticles is attributed mainly to the size, shape, type and ionic composition of the particles. Specically, the use of nanouids for heat augmentation and mass trans- port is of wide application and it is accruing interest from researchers. Nonetheless, experimental approach may be cumbersome and expensive. To this end, Lattice Boltzmann method (LBM) has shown its capability in the study of complex ow systems that have complicated geometries (e.g. porous media) with acceptable accuracy while using a simple algorithm. In this review, we present a rich summary of the latest ndings on the application of LBM fornanouids related heat and mass transfer processes with emphasis on porous media and also highlight current challenges for future research. © 2019 Elsevier B.V.

Introduction The signicance of nanoparticles (NPs) keeps gaining undaunted at- tention from researchers more than ever before due to its enormous ap- plications to virtually all disciplines. Fluids containing the suspension of these nanoparticles are referred to as nanouids [1,2]. In engineering, much attention is given to convective (free or forced) heat transfer en- hancement due to its practical applications in cooling and heating pro- cesses. Ellahi et al. [3] worked on structural effect of Al2O3-kerosine nanouid and established its potential for cooling liquid rocket engines; a vital nding in engineering. Nuclear reactors, heat exchanger, pane in- sulation panels, deposition instrument for chemical vapour, etc. all work on convective heat transfer mechanisms [4]. Alamri et al. [5] ascertained the signicance of nanouids for convective-radiation mechanism by examining the impact of some physical parameters on Plane Poiseuille Journal of Molecular Liquids 300 (2020) 112284 Corresponding author.
