Overview of Computational Fluid Dynamics Approaches

•Direct Numerical Simulation (DNS) –Theoretically, all turbulent (and laminar / transition) flows can be simulated by numerically solving the          full Navier-Stokes equations –Resolves the whole spectrum of scales. No modeling is required –But the cost is too prohibitive!  Not practical for industrial flows •Large Eddy Simulation (LES) type models –Solves the... Continue Reading →

Why vibration is important?

In many ways people can expect to obtain an ideal machine viewed from the angle of vibration , which is a machine that produces no vibration at all. Such an ideal machine will greatly save energy because of all the energy given to the whole machine will be used to perform the work alone, whether pumping a fluid, compressing the air, crushing paper etc. Without generating by products in the form of vibration. Apparently it is very unlikely because in terms of machining is not possible to get a very homogeneous material, fabrication machines without residual imbalance (residual unbalance) and rotating machinery moving and moving back and forth that does not cause friction with the other part. What is then seen as a result of the onset... Continue Reading →

Vibration Application (Modal Testing)

Modal testing can be applied for several purposes, including: • Diagnostic tools Modal testing can be used as a tool for diagnosing a failure of the structure, by knowing the characteristics of dynamic  structure by using the modal testing, the modal testing can be known personally frequency of the structure, obtained when a big frequency change...
