Analytical investigation of peristaltic nanofluid flow and heat transfer in an asymmetric wavy wall channel (Part II: Divergent channel)

Peristaltic motion of MHD nanofluid in an asymmetric micro-channel with Joule heating, wall flexibility and different zeta potential

“…By using cross-differentiation, we have eliminated the pressure term from the dimensionless Eqs. (17) and (18), and can write it as a single nonlinear differential equation. Now let us define Ψ , the stream function, as u = ∂Ψ ∂y , v = -∂Ψ ∂x , satisfying the continuity Eq.…”

“…Akbarzadeh et al [16] investigated the first two laws of thermodynamics for nanofluid flow with porous inserts and corrugated walls in a heat exchanger tube. In addition, Mosayebidorcheh et al [17,18] explained the peristaltic flow of nanofluid and heat transfer through asymmetric straight and divergent wall channels. Rahman [19] assumed the expansion/contraction of MHD nanofluid through permeable walls.…”

Design and testing of varying magnetic field effect in a pulsatility blood flow of viscoelastic material: Flexibility analysis in a curved channel

“…They 5 extended the previous research on a Jeffery fluid and integrated effects of slip and porous medium. Powell–Eyring nanofluid was taken in mixed convective peristalsis and the endoscopic effect was studied with the compliant walls by Hayat et al 6 Mosayebidorcheh and Hatami proposed two analytic investigations of a nanofluid in an asymmetric channel with wall properties, the first in a straight channel 7 and the second in a diverging channel 8 . Heat transfer reaction on Herschel Bulkley fluid motion in a nonuniform porous channel is investigated by Sakand and Patil 9 .…”

Entropy generation of turbulent Cu–water nanofluid flows inside thermal systems equipped with transverse-cut twisted turbulators

“…Passive techniques are effective methods to improve the heat transfer rate inside heat exchangers without changing the primary geometry of them. Several passive strategies have been employed by researchers in the past years to intensify the heat transfer and thermal efficiency parameter of those systems, like twisted tapes [1][2][3][4], wavy and grooved surfaces [5][6][7], hollow cylinders [8], baffles [9], nanofluids [10][11][12][13] and twisted transverse baffles [14].…”
