The development of dedicated CFD solver for aerodynamic analysis on internal and external flow
There are various engineering applications which required one has to solve an internal or an external flow problem. The design of flying vehicles such as aircraft, helicopter, missiles are examples which the ability to solve an external flow problem will determine the success in designing such …

New design of tuned vibration absorber for wide frequency range application
… (TVA) was chosen to be studied where the amount of vibration reduced was determined through finite element analysis (FEA) and validated with the experimental result. A actual scale of tuned vibration absorber was developed and applied on the structure to reduce the vibration. It is expected that …

Analysis of vortex shedding in a various body shapes
The study of various bluff body shapes is important in order to identify the suitable shape of bluff body that can be used for vortex flow meter applications. Numerical simulations of bluff body shapes such as circular, rectangular and equilateral triangular have been carried out to understand the …

Gas-liquid simulation of an airlift bubble column reactor
… such as bioprocess industries. The gas-liquid of two-phase fluid flow system has been carried out to investigate the hydrodynamics parameter. An Eulerian-Eulerian approach was used to model air as the dispersed phase within a continuous phase of water using the commercial software ANSYS FLUENT …

CFD simulation of the dynamic flow behavior in a bubble column reactor
… the hydrodynamic flow behaviors. Three types of gas distributor design are tested on the 1.5 m height and 0.15 m diameter bubble column cylinder. Five different velocities are used on the each gas distributor design in order to produces a variety flow pattern in the bubble column. The ANSYS …

Integrated protocol for ground and structures condition assessments using ambient vibration
… is no regular maintenance program or complete engineering record to carry out the re-evaluation work. Application of ambient vibration (AV) technique is widely used on ground and structures diagnosis works, but none of an effort to integrate them into a specific protocol. The main goal of this …

Simulation of palm oil and methanol mixing in stirred tank by implement a normal and fractal baffles
Numerical analysis of mixing and dissolution processes is becoming great significant for achieving a process of consideration and optimizing the production. Owing to the rising costs and deficiency of raw materials, “palm oil” processes are presently employed together with standard experimental …
