Interplay between Airy and Coriolis precessions in a real Foucault pendulum
N. N. Salva, H. R. Salva
We study the precession of a Foucault pendulum using a new approach. We characterize the support anisotropy by the difference between the maximum and minimum periods of the pendulu…
Auxiliary functions in the study of Stefan-like problems with variable thermal properties
Andrea N. Ceretani, Natalia N. Salva, Domingo A. Tarzia
We address the existence and uniqueness of the so-called modified error function that arises in the study of phase-change problems with specific heat and thermal conductivity given…
Determination and biological application of a time dependent thermal parameter and sensitivity analysis for a conduction problem with superficial evaporation
Natalia N. Salva, Maria S. Herrera, Andrea Monti Hughes +2
A boundary value problem, which could represent a transcendent temperature conduction problem with evaporation in a part of the boundary, was studied to determine unknown thermophy…
An exact solution to a Stefan problem with variable thermal conductivity and a Robin boundary condition
Andrea N. Ceretani, Natalia N. Salva, Domingo A. Tarzia
In this article it is proved the existence of similarity solutions for a one-phase Stefan problem with temperature-dependent thermal conductivity and a Robin condition at the fixed…
Approximation of the modified error function
Andrea N. Ceretani, Natalia N. Salva, Domingo A. Tarzia
In this article, we obtain explicit approximations of the modified error function introduced in Cho, Sunderland. Journal of Heat Transfer 96-2 (1974), 214-217, as part of a Stefan…
Existence and uniqueness of the modified error function
Andrea N. Ceretani, Natalia N. Salva, Domingo A. Tarzia
This article is devoted to prove the existence and uniqueness of solution to the non-linear second order differential problem through which is defined the modified error function i…
