In this paper, an asymptotic analysis of the Cartesian Graetz problem with third kind boundary condition is carried out. The analysis is performed using Leveque's asymptotic method, which is valid for regions near the duct entrance. The solutions for

The initial movement of a hanging string is revisited through an integral transformation, the analysis of the integral solution allows to obtain some exact solutions for the string profile and to understand the physical meaning of the solutions. Fina

We have numerically studied the fluid dynamics in a model of Teniente type copper converter with combined lateral and bottom gas injection. The three-dimensional simulation of the two-phase system was carried out using the volume of fluid (VOF) and t

The circular Sitnikov problem is revisited, using matched asymptotic expansions. In the case of large oscillation periods, approximate analytical expressions for the period and the orbit of the third body are found. The results are compared with thos

We study the structure of the seismic radiation in the far field produced by an explosive column. Using an asymptotic solution for the far field of vibration (Heelan’s solution), we find analytical expressions to the peak particle velocity (PPV) di

In this paper, we solve the Falkner–Skan equation with heat transfer through an expansion in Fourier series, results are improved by incorporating an asymptotic analysis for the Fourier series coefficients. The results show that the classical expan
