A Confirmed Model to Polymer Core-Shell Structured Nanofibers Deposited via Coaxial Electrospinning

Abstract EN

A model to core-shell structured polymer nanofibers deposited via coaxial electrospinning is presented.

Investigations are based on a modified Jacobi-Gauss collocation spectral method, proposed along with the Boubaker Polynomials Expansion Scheme (BPES), for providing solution to a nonlinear Lane-Emden-type equation.

The spatial approximation has been based on shifted Jacobi polynomials PT,N(α,β)(x) with α,β(−1,∞),T>0 was n the polynomial degree.

The Boubaker Polynomials Expansion Scheme (BPES) main features, concerning the embedded boundary conditions, have been outlined.

The modified Jacobi-Gauss points are used as collocation nodes.

Numerical examples are included to demonstrate the validity and applicability of the technique, and a comparison is made with existing results.

It has been revealed that both methods are easy to implement and yield very accurate results.
