Pressure inside the reactor was decreased to 1 10 m Torr by a vacuum pump and then 2 cm3/min helium flows into the reactor.
However, the mixed flow inside the reactor has disturbances such as by-pass and dead zones.
It was found that the mal-distribution of the gas flow inside the reactor can directly affect the performance of the reactor.
Thermo-fluid flow inside the reactor, the total energy absorption, radiation losses, absorption efficiency, and maximum temperature attained by the sample are predicted for different operating conditions.
Moreover, in order to obtain a description of the fluid flow inside the reactor, computational fluid dynamics (CFD) simulations were carried out.
The particularity of this process is that the gas flow inside the reactor is periodically reversed in order to trap the heat released during the reaction inside the process.
These two inlet flow conditions correspond, according to the computation of the MIVR fluid dynamics [26], to a laminar flow inside the reactor for 2 ml min−1 whereas a turbulent one for 20 ml min−1, with unsteady fluctuations of the flow.
The way out is to develop microchannel plates, which design would provide a countercurrent reagent flow inside the reactors.
Engineers had tried several times to retrieve the device, which was apparently jammed inside the reactor.
The model includes the unsteady solution of the turbulent flow field inside the reactor, the energy transport in the flow and the ensuing heat and mass transfer by convection over the MWM load.
