Modelling and Simulation

 

Modelling software: Ansys Workbench, Fluent and Static Heat transfer

Application 1: modelling of the impact that the configuration of the heating element have on the moving furnace on the temperature field

Model set-up

Heating element configuration 1

Heating element configuration 2

Temperature distribution under 800 ℃

Temperature distribution under 1200 ℃

Temperature distribution under 1500 ℃

Modelling software: Ansys Workbench, Fluent module

Application case: methane cleavage to prepare graphene

Modelling software: Ansys Workbench, Static Structure

Application : force analysis under structure design

Cracking furnace:

Model set-up

Total deformation result

Equivalent Stress Result

Temperature distribution and optimization scheme in the kiln:

Model set-up

Temperature distribution

Horizontal temperature distribution

Vertical temperature distribution

Conclusion 1: Furnace cover temperature zone : 2.8-3.3 meter from the surface (near the top ceiling)

Conclusion 2: increasing the thermocouple’s configuration density to 10 ( 5 cm apart on average), because the big temperature difference on top of the ceiling.
