Numerical investigation of hydrodynamics of batch crystallizer
Abstract: In this work, hydrodynamics in a draft tubebatch crystallizer is analysed computationally using Computational fluid dynamics (CFD). The CFD simulations are performed using multiple reference frame (MRF) with sliding mesh approach in transient condition for flow time of 5s using the standard k-ε turbulence model. The flow-field in batch crystallizer is quantified by calculating time averaged velocity profiles along the horizontal line and by analysing the temporal variation of liquid …

Retrofitting of Existing Building by Concrete Jacketing
Abstract: Seismic Retrofitting is engineered mitigation techniques for structural engineers. It is defined as the modification of existing structures to make them more resistant to seismic activity, ground motion or soil failures due to earthquakes. It is generally required for earthquake damaged and vulnerable buildings with no exposure to severe earthquakes. Retrofit enhances the structural capabilities of the building. In present time, there are many local and global retrofit techniques in …

A parametric study for the behaviour of steel plate-anchor assembly embedded in concrete under cyclic loading
Abstract: Steel plate-anchor assembly embedded in concrete is a common type of connection system used for connecting structural steel members to concrete members. These assemblies are subjected to different loading cases depending on their use. Since the behaviour of such assemblies is quite complex and depends on a number of factors associated with different components, it was decided to adopt finite-element technique to obtain a reasonably accurate analytical solution for the …
