Termoforeza je pojav, pri katerem se hitrost suspendiranega delca
v plinu s temperaturnim gradientom pospesuje v smeri upadanja
temperature. Pri normalnih MCVD delovnih razmerah je izkoristek
nanosa delcev samo funkcija ravnotezne temperature Te. Izkoristek
nanosa je 0,8(1-Te/Tr). Te pa je funkcija hitrosti gorilnika,
dolzine njegove poti, temperature okolice in debeline stene cevi.
Kljucne besede: opticno vlakno, termoforeza
Thermophoresis describes the phenomen in which a particle
suspended in a gas with a temperature gradient will acquire a
velocity in the direction of decreasing temperature. For normal
MCVD operating conditions, the deposition efficiency is only a
function of the equilibrium temperature, Te. The deposition
efficiency is 0,8(1-Te/Tr). It's determined that Te is a strong
function of the torch velocity, the traverse length, the
temperature of the ambient environment, and, the tube wall
thickness.
Key words: optical fibre, thermophoresis
