TRANSFERUL DE CĂLDURĂ ÎN PISTA PATINOARULUI ARTIFICIAL (Rezumat) Lucrarea prezintă modelarea transferului de căldură şi formarea gheţii în jurul ţevilor pistei unui patinoar artificial utilizând metoda elementului finit. Modelarea cu element finit a transferului de căldură în pista patinoarului permite calculul temperaturii, a vitezei de propagare a frontului de solidificare şi a ratei de solidificare în jurul ţevilor pistei. În cadrul studiului au fost comparate din punct de vedere al transferului de căldură două tipuri constructive de piste şi anume pista cu ţevi scufundate în apă şi cu ţevi îngropate in nisip.

FIZICĂ CONSIDERATIONS ON A BEHAVIORAL MODEL OF CAR PROPULSION SYSTEMS BY FLORIN POPA, EDWARD RAKOŞI * and GHEORGHE MANOLACHE “Gheorghe Asachi” Technical University of Iaşi, Department of Automotive and Mechanical Engineering Received: 24 March, 2012 Accepted for publication: 6 April, 2012 Abstract. Several of phenomena occur during operation of car propulsion systems and are influenced by many factors. This paper presents a unified approach to these problems. This work generates a mathematical model of a complex pattern study, for further development through a software package. Key words: behavioral model, car propulsion systems. 1. General Considerations In the proposed modelling is adopted as a key assumption that the entire car's propulsion system is a mechanical system consisting of solid bodies, connecting inner and outer, with a rigid motion, as outlines in Fig. 1. Fig. 1 – Mechanical equivalent of the entire system of the vehicle propulsion. * Corresponding author: e-mail: edwardrakosi@yahoo.com
