...Shou-Fu Tian; Xiao-Fei Wang; Tian-Tian Zhang; Wang-Hua Qiu Purpose The purpose of this paper is to study the stability analysis and optical solitary wave solutions of a (2 + 1)-dimensional nonlinear Schrödinger equation, which are derived from a multicomponent plasma with nonextensive distribution...

... difference method. Excellent agreement is obtained between the numerical solution under zero wave amplitude and the exact solution of the plain fin. Findings – The following wavy fin types and conditions are found to produce larger heat transfer rate and its volumetric value than those for the plain...
