The valve body or Pressure vessel will be analyzed for a given load condition as per ASME Design by analysis for pressure vessel. The sections will be linearized to define the membrane and bending stress to compare with the ASME allowable stress, according to the procedure described in ASME VIII Div.2 2007. The numerical analysis […]

Inorder to reduce higher cooling demands for buildings or industries, passive cooling by night-time flushing can be seen as a promising option. Particularly in tropical and sub-tropical climates where the difference in peak day-time and night-time temperature is about 10˚C – 13˚C. Those buildings with high thermal mass benefit the most in this type of

Earthquake Resistant Design (Seismic Analysis) Buildings response to earthquakes is a dynamic phenomenon, but structures are mainly designed to resist static loads. The method of neglecting the dynamic forces becomes the cause of disaster during a seismic event. The recent Nepal earthquake occurred in July 2015 has created a need and mandatory implementation of Earthquake

Why is Acoustic Modelling important? Acoustic waves are pressure pulses travelling through a compression medium at the speed of sound in that medium. Predicting valve acoustics is very tedious and costly for running experiments in laboratory inorder to evaluate the effectiveness of one design over the other. Predicting valve acoustics using CFD has become possible
