Introductory Chapter: Fluid Flow Problems

Abstract

In many real life problems, heat transfer is an important issue and becomes a challenge for the engineers and industrialists. In order to overcome this challenge, one of the methods, which is commonly in use, is to increase the available surface area of heat exchange [1–4]. Hussanan et al. [5] studied the use of oxide nanoparticles for the energy enhancement in water, kerosene, and engine oil-based nanofluids. Tesfai [6] experimentally investigated graphene and graphene oxide suspension for thermal management application. Shafie et al. [7] are considered the first who reported a theoretical study on molybdenum disulfide ( MoS 2 ) nanoparticle suspended in water-based nanofluid in a channel. Khan et al. [8] and Khan [9] also analyzed Molybdenum Disulfide nanofluids in a vertical channel with various effects. Few other interesting investigations in this direction are those made by Wu and Zhao [10], Khan [11], Ali et al. [12] Sheikholeslami and Bhatti [13], Rashidi et al. [14], Mahian et al. [15], and Kasaeian [16].
