Abstract
The linear theory of heat and mass transfer is considered. Some general theorems are formulated, i.e. a reciprocity theorem and a variational theorem (no use is made of the Laplace transform). The functional derived herein gives all the governing equations, including the boundary and initial conditions, as Euler equations. On considère la théorie linéaire du transfert de chaleur et de masse. Quelques théorèmes généraux sont formulés tels que, par exemple, un théorème de réciprocité et un théorème variationnel (il n'est pas fait usage de la transformation de Laplace). La fonctionnelle utilisée donne toutes les équations fondamentales qui incluent les conditions aux limites et initiales, comme les équations d'Euler. Die lineare Theorie des Wärme- und Stofftransports wird betrachtet. Einige allgemeingültige Theoreme werden formuliert, z. B. ein Reziprozitätstheorem und ein Variationstheorem (die Laplace-Transformation wird nicht verwendet). Das hier hergeleitete Funktional ergibt alle maβgebenden Gleichungen sowie die Rand- und Anfangsbedingungen und die Euler-Gleichungen. pACCмAтpHBAeтCя лиHeйHAя тeopия тeплo- и мACCoпepeHoCA.
