Experimental and Numerical Studies of Droplet and Particle Formation in Electrohydrodynamic Atomization

Hua J., Lim L.K., Wang C-H, Institute of High Performance Computing, SG

Electrohydrodynamic Atomization (EHDA) is a method to disperse liquid jet into micro- droplets where an electrical field is applied to control the breakup characteristic of the liquid jet. Recent studies show that EHDA method is [...]

Numerical simulation of the droplet generation mode transition of the co-flowing liquids in micro-channel

Hua J.S., Cheng M., Liu T.G., Institute of High Performance Computing, SG

A front tracking method based multiphase flow simulation (Unverdi and Tryggvason, 1992) is adopted to investigate the transition mechanism of droplet formation modes of dripiing and jetting. The numerical method solves a single set of [...]

Three-Dimensional Transient Motion of Spherical and Deformable Droplet in L-Shaped Rectangular Microchannel

Kang C.W., Hua J.S., Lou J., Institute of High Performance Computing, SG

Three-dimensional transient motion of spherical and small deformable droplet in an L-shaped rectangular channel is investigated numerically. The methodology employed is front tracking coupled with the parallel adaptive refinement meshing code, referred as PARAMESH. The [...]

Full Coupling Simulation of a Membrane Micropump

Yao Q., Xu D., Pan L.S., Melissa Teo A.L., Ho W.M., Peter Lee V.S., Shabbir M., Institute of High Performance Computing, SG

The design of PZT actuated valveless membrane micropumps is a very complex process as it involves the knowledge of electro mechanics, solid mechanics and fluid mechanics. So far, there is no accurate, flexible and broadly [...]

Effects of Temperature and Shape on the Tensile Behaviour of Platinum Nanowire

Koh S.J., Lee H.P., Lu C., Cheng Q.H., Institute of High Performance Computing, SG

This paper presents a classical MD simulation on the tensile behaviour of Pt NWs with round and square cross-sections, with characteristic dimensions of 1nm. The simulations will be performed at room temperature (300K) and an [...]

A Molecular Dynamics Simulation of Multi-wall Platinum Nanowires

Cheng Q.H., Lee H.P., Lu C., Koh S.J., Institute of High Performance Computing, SG

This paper aims to study structural formation and mechanical properties of platinum (Pt) Nanowire (NW) using the classical molecular dynamics (MD) simulation method. A type of multi-shell Pt NWs is obtained from the simulations. These [...]

Proper Orthogonal Modes for Macromodel Generation for Complex MEMS Devices

Lin W.Z., Lee K.H., Lim S.P., Institute of High Performance Computing, SG

In this paper, a novel method for macromodel generation for the dynamic analysis of structurally complex MEMS devices is developed by making use of proper orthogonal decomposition (POD) and classical component mode synthesis (CMS). The [...]

Simulation of Self-Assembly of Quantum Dots in Superlattices

Liu P., Wang Y.Y., Lu C., Institute of High Performance Computing, SG

The self-organization of three dimensional quantum dot superlattices that spontaneously form during heteroepitaxial growth is investigated by using a three dimensional kinetic model. The model predictions show that the multilayer arrays of quantum dots can [...]

Computation Speedup of Macromodels for Dynamic Simulation of Microsystem

Lin W.Z., Lee K.H., Lim S.P., Institute of High Performance Computing, SG

A doubly clamped microbeam actuated by electrostatic force with squeezed gas film damping is a well-known micro device for many researchers to demonstrate how reduced-order dynamic macromodels are an effective way to faithfully capture the [...]
