Every project is different. That’s why Beaumac prides itself on finding custom solutions to a wide variety of graphite manufacturing projects. Here’s one example.
Resistance heating elements normally can be engineered with simple algebraic calculations. Rarely, unusual requirements demand more intensive methods. In these cases, finite element methods can be applied to map out voltage, current and power distribution in a heater system and used to guide the design process.
The following figures show sequentially a refined finite element mesh, voltage distribution (lines of equipotential) and the resulting power density distribution in a small section of a crystal growing heater.
