Blog Summary Flow frequencies in a duct flow if in-phase with structural eigen frequencies, can cause severe vibrations. Reduction or complete elimination of such flow induced vibrations might not even require major structural modifications! Table content Explanation Duct Flow Analysis Explanation : Flow frequencies in a duct flow if in-phase with structural eigen frequencies, can cause severe vibrations. Reduction or complete elimination of such flow induced vibrations might

Blog Summary Strainers are used in processing plants and chemical industry as a filtering device. The filtration process involves flow through narrow passages, which causes high pressure drop or head-loss. Computational Fluid Dynamics (CFD) is useful to understand the cause of pressure drops in industrial strainers. Table content Explanation Challenges Results Explanation : Strainers are used in processing plants and chemical industry as a filtering device. The filtration pr

Blog Summary Cyclone separators are used for the purpose of separating dust particles from gas streams. It works on the principle of centrifugal force generated by vortex created due to tangential entry of fluid. CFD analyses can help in visualizing the flow-field inside the cyclone separator along with estimation of the collected and leaked particles. A high overall collective efficiency (98.3%) has been observed owing to the high centrifugal force experienced by the dust pa

Blog Summary A CFD study where flue gases emanating from three stacks of a captive power plant is described Dispersion of pollutants are best described as two-phase flows. The contours of phase volume fractions can be plotted to look after the concentration variation near the stacks. Table content Explanation CFD Study Explanation : Dispersive transport takes place as a dispersed phase moves into a continuous phase available in its surroundings. The dispersion of pollutants f

Blog Summary All the variables are not equally responsible for system's behavior, so it can be really helpful if the total number of variables to be monitored to a few important ones. ML techniques which can really help in determining the minimum set variables which largely captures the process behavior. Table content Explanation Explanation : Machine Learning can help in process monitoring in various ways. In a typical process plant there are many process variable are to be

Blog Summary In process and manufacturing industries it is not always feasible to measure every variables of interest. In process industries soft sensors can be really helpful in monitoring complex processes. Table content Explanation Explanation : In process and manufacturing industries it is not always feasible to measure every variables of interest. In those scenarios soft sensors can be really helpful. So, Soft sensors, also known as virtual sensors, are models used to es

Blog Summary Electro-Static Precipitators (ESPs) remove particulate matter from a gas stream by a series of corona generating electrodes and collector plates. CFD analysis can be used to optimize the collection efficiencies in ESPs. Table content Explanation Open Area Ratio (OAR) Explanation : Electro-Static Precipitators (ESPs) remove particulate matter from a gas stream by a series of corona generating electrodes and collector plates. Several factors like flow rate, particu

Blog Summary Cyclone separators are prevalent in process industries separation process. Pressure looses due to flow path can also be estimated from CFD studies. Table content Explanation Case Study Explanation : Cyclone separators are prevalent in process industries for separating oil droplets or dust particles from gases. These work on the principle that centrifugal force on a particle is proportional to its mass. So higher the mass, higher the centrifugal force. In cyclone
