Abstract
An analytical solution is proposed to predict the fully developed Nusselt number for laminar flow in circular pipes, as arising from exponential heating. The solution is obtained in terms of Confluent Hypergeometric Functions, characterized by fast convergence and easy implementation. Both positive and negative exponents are considered. The range of practical interest is discussed. © 1995.File in questo prodotto:
