Unsteady MHD free convection flow past a vertical permeable flat plate in a rotating frame of reference with constant heat source in a nanofluid

Abstract

The unsteady magnetohydrodynamic flow of a nanofluid past an oscillatory moving vertical permeable semi-infinite flat plate with constant heat source in a rotating frame of reference is theoretically investigated. The velocity along the plate (slip velocity) is assumed to oscillate on time with a constant frequency. The analytical solutions of the boundary layer equations are assumed of oscillatory type and they are obtained by using the small perturbation approximations. The influence of various relevant physical characteristics are presented and discussed.

Chemical reaction and radiation absorption effects on the flow and heat transfer of a nanofluid in a rotating system

“…These figures illustrate this agreement with the physical behavior. These results are related to those obtained by Satya Narayana et al (2013a), (b) and Hamad and Pop (2011). The influence of the chemical reaction parameter Kr on the nanofluid velocity and temperature profiles, respectively, for the Cu nanofluid particles ð/ 6 ¼ 0Þ and water as the base fluid ð/ ¼ 0Þ is illustrated in Fig.…”

“…In the present study we have chosen n ¼ 10, nt ¼ p=2, Pr ¼ 6:2, e ¼ 0:02, while Kr, F, R, M, S, Q H , Q l , Pr and Sc are varied over a range, which are listed in the figures legends. A comparison of the present results of skin-friction coefficient and rate of heat transfer with those of Satya Narayana et al (2013b) and Hamad and Pop (2011) is provided in Table 2 for different values of Prandtl number. This table clearly displays that tremendous conformity exists between the results.…”

MHD boundary layer flow and heat transfer characteristics of a nanofluid over a stretching sheet

“…Aminossadati et al [28] studied the heat transfer performance of water−Al 2 O 3 nanofluid in a horizontal microchannel that is under the influence of a transverse magnetic field. Recently, Hamad and Pop [29] studied the unsteady magnetohydrodynamic flow of a nanofluid past an oscillatory moving vertical permeable semi-infinite flat plate with constant heat source in a rotating frame of reference.…”

Heat and mass transfer on MHD nanofluid flow past a vertical porous plate in a rotating system

“…It is worth mentioning that the nanofluid model proposed by Buongiorno (2006) is used by many recent studies (Rana and Bharava, 2012;Alsaedi and Hayat, 2012;Hajipour and Molaei Dehkordi, 2012). However, we are following the nanofluid model proposed by Tiwari and Dass (2007), which is being used by many current researches Hamad and Ferdows (2012); Norifiah Bachok (2012); Hamad and Pop (2011) on various flow fields. The layout of the paper as follows.…”
