CFD simulation time consumption is mainly dependent on the number of nodes/elements of meshing, the number of iterations and computational power available. For a simple model (e.g. a cube), simulation can take a few minutes or even up to hours to complete, for a more complex model (e.g. FPSO) may take up to several days...Continue Reading

Some examples of readily available in market CFD tools are Ansys, OpenFOAM, ParaView, SOLIDWORKS, Autodesk CFD.Continue Reading

CFD analysis comprises of several component: 2D/3D model development, meshing, solver setup & calculations, and post-processing.Continue Reading

CFD simulation enables visualisation of simulation results in 2D or 3D form without requiring to conduct a physical experiment which can be time-consuming at the same time cost-inefficient and could potentially extremely hazardous.Continue Reading

Computational fluid dynamics (CFD) refers to an approach that analyses and solves problems that involve fluid flows.Continue Reading

Computational Fluid Dynamics (CFD) modelling refers to the simulation of fluid and/or gases based on the principles of fluid mechanics, utilising numerical methods and algorithms.Continue Reading

Normally sound below 85dB would be acceptable for exposure of 8hrs/day. Noise above 140dB can be considered intrusive and normally not acceptable at any time without PPE.Continue Reading

dB = 10*log10(P1/P2) where P are relative power or soundContinue Reading

The method and instrument to be used is depending on the aim of the noise measurement. For personnel exposure, Dosimeter, Integrating Sound Level Meter or Sound Level Meter can be used. For Noise Survey or Noise Level Generated by Noise Source, ISLM or SLM can be used.Continue Reading

A noise assessment is an examination of the nature and characteristics of noise.Continue Reading
