Heat Transfer to Polymer Melts Flowing in a Circular Duct

Research of thermal conductivity of the condensed mass of the whole waste tires and determination of their optimum arrangement in the pyrolysis reactor

“…where r, z -cylindrical coordinates; r, q -spherical coordinates; T -temperature; t -time, c=rc -volumetric heat capacity; r -density of the mixture of the tire components in the third zone; с -mass heat capacity [14].…”

“…The theoretical study of the heat transfer process is performed on an idealized model of the structure, which reflects the basic geometric characteristics of the real tire cell regarding all significant factors that determine the heat transfer process. Such a model can be considered adequate to the real system [14].…”

Exact solution of heat transfer problem for generalized Newtonian flow between two infinite parallel plates

“…The Fourier method is widely used to solve heat transfer problems in analytical form for the flow of both Newtonian and non‐Newtonian fluids with constant thermophysical properties. Almost all of them are devoted to the case of fluid flow in circular pipes, i.e.…”

“…The expression for the velocity profile can be obtained only for cases when rheological equations of state are in their simplest form (for example, power‐law fluid). Some heat transfer problems for the power‐law fluid were studied by Bird, Lyche, Hirai, Michiyoshi et al, Parikh et al, and Froishteter et al The Bubnov‐Galerkin method was used by Tyabin et al to determine the eigenvalues. Gottifredi et al used a method involving Laplace transforms to solve the same problem.…”
