A novel analysis for calculating the smallest envelope shape of wet fins with a nonlinear mode of surface transport

Kundu, Balaram; Lee, Kwan-Soo - In: Energy 44 (2012) 1, pp. 527-543

A solely analytical method is investigated to determine the minimum fin shape of wet fins subject to variable heat transfer coefficients. The analysis is applicable to any surface condition, including dry, fully wet and partially wet. An optimization procedure based on the variational principle...

Approximate solution of linear ordinary differential equations with variable coefficients

Li, Xian-Fang - In: Mathematics and Computers in Simulation (MATCOM) 75 (2007) 3, pp. 113-125

In this paper, a novel, simple yet efficient method is proposed to approximately solve linear ordinary differential equations (ODEs). Emphasis is put on second-order linear ODEs with variable coefficients. First, the ODE to be solved is transformed to either a Volterra integral equation or a...
