  • Computer Simulation of Centrifugal Casting Process Using Flow-3D
    Materials Science Forum, 2015
    Co-Authors: J. Aneesh Kumar, Kalmanje Krishnakumar, S. Savithri
    Abstract:

    Centrifugal casting Process is one of the potential manufacturing techniques used for producing functionally graded materials viz., composite materials or metallic materials which have high differences of density among constituents. In this Process, the fluid Flow plays a major role and understanding the Complex Flow Process is a must for the production of defect-free castings. Since the mold spins at a high velocity and the mold wall being opaque, it is impossible to visualise the Flow patterns in real time. Hence, in the present work, the commercial CFD code Flow-3DTM, has been used to simulate the mold filling sequence for a simple hollow cylindrical casting during vertical centrifugal casting Process. Effect of various spinning velocities on the fill pattern during vertical centrifugal casting Process is being investigated.

  • Policies for managing peak stock of food grains for effective distribution: A case of the Indian food program
    Socio-Economic Planning Sciences, 2020
    Co-Authors: Maheswar Singha Mahapatra, Biswajit Mahanty
    Abstract:

    Abstract The Indian food program has encountered a significant shortfall in storage due to slow expansion of storage facilities in comparison with procurement. The open storage of food grains results in substantial loss and deterioration of quality. While increasing storage capacity is a viable but costly and time consuming option, the adoption of policies for peak storage reduction would go a long way towards effective food grains management. On this background, this study proposes policy adoption for peak storage reduction for effective inventory management. A dynamic simulation model was built by replicating the Complex Flow Process and incorporating the Process variability for finding the bottleneck and significant factors. It was found that steep wheat procurement is the critical bottleneck factor for peak storage requirements. Two practical and straightforward, yet effective policies are proposed from the few existing strategies for peak storage reduction owing to the constraints associated with the food program. With the actual data of the food program, reduction in peak stock was estimated for the recommended policies, including the operational cost saving in storage. The practical implications of these policies within the system were also discussed. Through peak reduction, the use of open storage can be significantly reduced, and this leads to better food grains management for effective food distribution.
