Polymer Rheology and Fluid Mechanics Syllabus for B.Tech 5th sem is covered here. This gives the details about credits, number of hours and other details along with reference books for the course.
The detailed syllabus for Polymer Rheology and Fluid Mechanics B.Tech (R13) fifthsem is as follows
OBJECTIVE: To enable the students to understand mechanical behaviour of polymeric materials under applied load for short term and long term Flow behavior of polymer melts and the experimental techniques for measuring the rheological properties.
UNIT I [9 Hours]
Introduction and Basic concept of Rheology, classification of fluids, Newtonian and non Newtonian fluids, shear stress, shear strain and shear rate, shear modulus, bulk modulus, Zero shear viscosity, Dependence of viscosity with temp, shear stress, shear rate fluid through channel- Viscoelasticity – effect of rate of strain, temperature and time on mechanical behaviour of polymeric materials
UNIT II [9 Hours]
Mechanical models – stress strain response of spring and dashpot – viscoelstic models Maxwellc element – Voigt kelvin element – response to creep and stress relaxation -four-parameter model – dynamic mechanical properties – Boltzman principle – time temperature super position principle – WLF equation.
UNIT III [9 Hours]
Viscosity of polymer melts – die- swell and melt fracture – Weissenberg effect – Elongational viscosity. Measurements of rheological properties – capillary rheometers – cone and plate viscometer – torque rheometers – Mooney viscometer – Applications of rheology to polymer processing (injection moulding, extrusion and blow moulding)
TOTAL : 45 PERIODS
OUTCOMES: Upon completing this course, the students
- Will understand the influence of rheology in polymer properties.
