On the Mathematical Analysis and Optimization of Chemical Vapor Infiltration †
In this paper we present an analysis of the partial differential equations that describe the Chemical Vapor Infiltration (CVI) processes. The mathematical model requires at least two partial differential equations, one describing the gas phase and one corresponding to the solid phase. A key difficulty in the process is the long processing times that are typically required. We address here the i...
متن کاملModelling of Pyrocarbon Chemical Vapor Infiltration
The chemical vapor infiltration (CVI) of pyrocarbon is used to produce carbon matrix of C/C composites. This process involves complex physico-chemical phenomena such as the transport of gas mixtures (hydrocarbons and hydrogen) in the reactor and inside the fibrous preform, chemical reactions (pyrolysis and deposition), and the structural evolution of the preform. A global modelling approach has...

there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...
Growth of Pyrocarbon by Multi-Physics Fields Chemical Vapor Infiltration
A novel rapid chemical vapor infiltration (CVI) processing defined by multi-physics fields CVI was used to fabricate carbon/carbon (C/C) composites. Liquid petrol gas is used as carbon source and the parameters were experimental tested and optimized. The influence of temperature and pressure on the growth of pyrocarbon was investigated in detail. Because of the influence of multi-physics fields...
متن کاملOptimization of Chemical Vapor Infiltration with Simultaneous Powder Formation
A key difficulty in isothermal, isobaric chemical vapor infiltration is the long processing times that are typically required. With this in mind, it is important to minimize infiltration times. This optimization problem is addressed here, using a relatively simple model for dilute gases. The results provide useful asymptotic expressions for the minimum time and corresponding conditions. These a...
