MORENO, Juan C; OCAMPO, Jackson  y  GIRALDO, Liliana. Simulation of a Calorimetric Cell using Finite Elements. Inf. tecnol. [online]. 2007, vol.18, n.2, pp. 25-35. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642007000200004.

Finite elements have been employed in this work with the purpose of determining the convenience of using a parallelepiped geometry and different materials for a cell of a Calvet type conduction microcalorimeter. The heat equation allows to describe isotherm curves established inside the calorimetric cell during the heat transfer process. The existence of critical points in the geometry of the cell can affect the measuring process and be an factor of error during experimental data acquisition. The simulation allows to determine the feasibility of diminishing these effects by changing the construction materials.

Palabras clave : conduction cells; Calvet type calorimeter; heat equation; finite elements.
