Abstract

Wiji Mangestiyono, in paper airfoil design use caedium software explain that caedium and its add-ons combine to form an easy-to-use Computational Fluid Dynamics (CFD) software system that can help to assess the performance of  3D model. Using Caedium add-ons can create any 2D or 3D geometry or import geometry from another CAD package. Then simulate how a gas (e.g. air) or liquid (e.g. water) will flow over and through  geometry. Caedium is simple to learn and efficient to use. Every body can study how the physics of its model changes over time or as modify the model in real time. Caedium's unified simulation environment makes it easy to change the model on the fly and quickly see the results of the changes. Keywords : Caedium, Airfoil, Computation Fluid Dynamics

Abstract

Wiji Mangestiyono, , A.P. Bayuseno, Stefanus Muryanto, in this paper explain that the problem of gypsum scaling becomes a trouble for some industry in which use some water for its system. Some disadvanteges come up because of : the time of industrial process will be more longer and production cost increase necesery.To prevent the growth of scale, the experiment must be done. Researcher try to answer this problem so an experimental about kinetic study of gypsum scaling established. Flowrate would be a parameter with assume that it has effect on reaction flow. The result of  this experiment are : reaction rate increase when flow rate increase; adition some aditives becomes reaction rate decrease. Keywords : crystal, flow rate, reactio rate, gipsum
