Entropy Generation in a Viscoelastic Fluid Squeezed and Extruded Between Two Parallel Plates
Аннотация
There are several engineering devices where simultaneous
squeezing and extrusion of viscoelastic fluids take place.
Thermodynamic analysis of these phenomena are important
from the context of designing of these devices as these involve
generation of several irreversibilities. In the present theoretical investigation, we extensively analyse the entropy generation characteristics of such devices through Oldroyd-B model. We represent the combined effects of fluid rheology, and
squeezing-extrusion mechanism on the entropy generation
characteristics. The thermodynamics performances of these
engineering devices with applications having simultaneous
squeezing and extrusion of viscoelastic fluid can be enhanced
through process parameter optimization using our study.
