Numerical simulation of heat transfer effect on Oldroyd 8-constant fluid with wire coating analysis

Solution of magnetohydrodynamic flow and heat transfer of radiative viscoelastic fluid with temperature dependent viscosity in wire coating analysis

“…Shah et al [ 32 ] investigated the third grade in the absence of magnetic field for wire coating process. Bhukts et al [ 33 ] investigated heat transfer effect on Oldroyd 8-constant fluid with wire coating analysis. Nayak et al [ 19 ] studied wire coating analysis using MHD third grade fluid with temperature dependent viscosity.…”

“…The governing equations for incompressible viscoelastic PTTF are 5–11 The substantive acceleration, denoted by D/Dt, is made up of the local derivative normal∂/normal∂t and the convective derivative u.normal∇, that is, DDt=normal∂∂t+u.normal∇.…”

“…The distribution of fluid velocity and temperature is taken into account. The PTT model, which is represented in the work of Mahanthesh et al and others, 7–11 was used to show the viscoelastic properties of the fluid. where η denotes the viscosity coefficient of the fluid, λ signifies the relaxation time, trS represents the trace of stress tensor S , and A1 characterizes the distortion rate tensor provided by The stress tensor S is given by The upper convected derivative S∇ in equation (4) is given as The function f is given by ffalse(trSfalse) is the stress function in equation (10), where the fluid's elongation behavior is linked to ε. The model simplifies to the well-known fluid model when ε=0, and to the Newtonian model when λ=0.…”
