Analytic-Numerical Solution of Random Boundary Value Heat Problems in a Semi-Infinite Bar

Abstract EN

This paper deals with the analytic-numerical solution of random heat problems for the temperature distribution in a semi-infinite bar with different boundary value conditions.

We apply a random Fourier sine and cosine transform mean square approach.

Random operational mean square calculus is developed for the introduced transforms.

Using previous results about random ordinary differential equations, a closed form solution stochastic process is firstly obtained.

Then, expectation and variance are computed.

Illustrative numerical examples are included.
