Abstract
Elemento intercambiador térmico para aparatos de calefacción, provisto de paredes que forman un conducto tubular, destinado a un intercambio térmico entre aire a calentar que circula por convección alrededor de este elemento y gases calientes de combustión que circulan por su interior, caracterizado por que es doble en el sentido de que cada una de sus paredes mayores activas, de intercambio, perpendiculares a un plano longitudinal de simetría, comprende, por una parte, cerca de cada uno de sus extremos, dos series de aletas externas simétricas y oblicuas con respecto a este plano, siendo diferente la oblicuidad de una aleta a la otra de manera que cada serie de aletas provoca un cambio de dirección, sensiblemente de 90º, en el aire circulante en su contacto, y, por otra parte, esencialmente en toda su longitud, una línea media de aletas externas planas, situadas dentro del citado plano, para separar, en dos corrientes independientes de convección, simétricas con respecto al citado plano, el aire que circula a ambos lados de ellas.

Approximation methods of solving the heat conduction equation are based on consideration of two problems, the convective fin and the plane semi-infinite solid under transient heating
Laminar convective heat transfer in the entrance region bounded by parallel flat plates at constant temperature(Energy equation for laminar convective heat transfer in combined hydrodynamic and thermal entrance region bound by parallel flat plates)
Heat transfer in thermal entrance region with laminar slip flow between parallel plates at unequal temperatures(Forced-convection heat-transfer characteristics for incompressible laminar flow between parallel walls with unequal temperatures under conditions of low gas density)
Some problems in the theory of heat conductivity of temperature pickups in the measurement of unsteady temperatures(Unsteady heat transfer analysis of pickups for time-variable temperatures, noting armoring, radiative heat exchange and other effects)
