Gating design can be improved by
incorporating additional factors of kinetic
energy, pressure difference and sur face
energy related to liquid metal flow in circular
mold sections with classical Bernoulli’s fluid
flow principal. The developed mathematical
modelling was experimented using simulation
method in annular thin section of glass tubes
with water and kerosene. To make the modelling
relevant for hot clay molded investment casting
production actual design was done in those
molds for few brass castings. Simulation
experiments provided good agreement and
designed castings also produced good sur face
finish as well as satisfactory metal product.
