| Summary: | This paper presents the modeling the drying process of shell mould layering process for
the ceramic shell mould fabrication process. As this process involves the repeated drying of the
different wetted/saturated layers, therefore modeling of this phenomena involve a sequent approach
to tackle the whole development of shell mould layering process. In this work an Ab-Initia approach
was selected as the best simulation technique to map the drying mechanism. Saturation or moisture
content was selected as the best parameter that will represent the drying of layering process. Using
FEM with quadrilateral shape mapping of several interested points were selected to predict the
moisture/saturation movement during the drying of shell layering stages. Standard drying time with
2 hours and early drying time were chosen to measure the moisture movement as layer added to the
previous dried coated shell or layers. This complex mechanism of drying and penetration layering
shell were then numerically solve with fully implicit backward time stepping scheme. Hopefully,
this model and can be used to measure the complex movement of the main parameter i.e
saturation/temperature in the drying process of multilayer system which is sometimes impossible
directly measured under experimental technique |
