CFD Analysis of Effect of Forced Vibration on Heat Transfer in Laminar Flow
Abstract: Vibration of pipes conveying fluid is an important problem present in installations which are normally used in petroleum industries, hydropower systems, food processing industries, chemical plants and hydraulic power systems. Research is needed to further understand and be able to predict the flow behavior and investigate ways of improving their processing. The current work involves the numerical simulation of flow and heat transfer under an externally imposed mechanical vibration. CFD …

Design of Sleeve for Multi-barrel Pellet Injector System: A Review
Abstract: A multi-barrel pellet injector system has been developed for plasma fueling of the tokamak fusion test reactor (TFTR). This paper describes the different arrangement of barrels along with design of sleeve for holding the barrels, for production and acceleration of pellets of different sizes. The in situ pipe gun concept with the use of compact cryo-coolers enables stable operation as a fundamental facility in plasma experiments. Pellets are accelerated in …

Numerical Study of Heat Transfer in Six Channeled Dimpled Plate Heat Exchanger
Abstract: Heat transfer augmentation is the most important criteria in many chemical, pharmaceutical and mechanical industry sectors. Considering this factor into account, heat transfer surface modification is being done for heat transfer augmentation purpose. Making dimples on heat transfer surface is one such augmentation technique. This study presents numerical analysis of six channeled counter current dimpled plate heat exchanger, in which the relative depth (dimple depth to diameter ratio (δ/D)) is …

Hysteresis Current Control Based Grid Connected PV System by using Bidirectional DC-DC Converter
Abstract: This paper proposes a control strategy for the operation of solar energy generation integrated with grid. Boost converter is used to extract the maximum power from the available solar power. The buck converter and bi-directional DC/DC converter connected with common DC bus and it’s connected with different loads. MPPT algorithms have been used in PV systems to deliver the maximum available power to the load under changes of the solar …
