Perhaps the most obvious myth is that graphics calculators are mainly useful for drawing graphs of functions and hence are not relevant to most mathematics curricula. An hour or two with a modern graphics calculator will quickly dispel this myth. For example, my book, More mathematics with a graphics calculator: Casio cfx-9850G, contains sixteen chapters, only four of which are primarily concer...

Three different test cases involving free surface flows with surface tension were investigated with ANSYS CFX. Transient analyses were performed in all cases. The three cases were: (1) oscillations of a twodimensional cylindrical rod; (2) rise of liquid in a capillary; and (3) rise of an air bubble train through stagnant water. The mesh resolution, timestep, and solver settings required to obta...

The Inject Pipe Mixer (IPM) are being used as venturi injectors and can also homogenize two fluids. The entry of secondary fluid as a jet influences flow field in the device. A CFD simulation of flow through an IPM (Lshape) has been carried out using ANSYS CFX 11.0 using water as the flowing fluid to understand the flow field under turbulent flow conditions using standard k--ε model. The result...

Porous dielectrics such as SiCOH are used as the insulator in interconnect wiring in microelectronics devices to lower the dielectric constant and therefore decrease the resistive–capacitive delay. After etching a trench in low-k dielectrics in fluorocarbon plasmas, a CFx polymer remains on the sidewalls, which must be removed in a manner that does not damage the low-k material. This can be acc...

Traditionally the resistance of ships has been determined using towing tank experiments. Over the past two decades increased computational power has allowed numerical approaches to replicate and potentially start to replace towing tank experiments. This work investigates the quality of results that can be achieved using a commercial Reynolds Averaged Navier Stokes (RANS) flow solver, ANSYS CFX ...

Carbon-based thin films are a vast group of materials of great technological importance. Thanks to the different bonding options for carbon, a large variety of structures (from amorphous to nanostructured) can be achieved in the process of film synthesis. The structural diversity increases even more if carbon is combined with relatively small quantities of atoms of other elements. This results ...
