The work offers a thorough investigation of nanofluid-based heat transfer analysis in porous media. Due to their improved thermal properties, nanofluids, which are colloidal suspensions of nanoparticles in base fluids, have attracted a lot of attention lately. An in-depth investigation of the existing research on employing nanofluids to improve heat transmission in porous media is the goal of this review. The concept of heat transmission in porous media and its use in numerous engineering applications are introduced in the opening paragraphs of the article. The description and features of nanofluids are then covered in depth, stressing the special qualities that make them appealing for applications involving heat transfer
