Transonic Flow Past Conically Cambered Wings
Abstract: The flow is analysed over conically cambered wings for transonic flow conditions. Wing Planform is conically cambered for supersonic flow for minimum induced drag. The circulation to determine the forces is developed using panel methods. Objective function for drag minima is formed using Lagrange multipliers. The transonic flow computations are progressed through computational fluid dynamics. In case of a subsonic leading edge in supersonic flow there is no shock wave …

Fuzzy Logic and Internet of Things based Automatic Three Phase Changeover
Abstract: Three phase supply is preferred over single-phase supply not only in commercial sector but also in residential sector due to its ability of supplying uniform and less fluctuating power. However phase cuts or phase failure may occur in a three phase supply due to a disturbed transformer or any other technological factor. This generally renders one phase inoperative. A commonly available solution is manual three phase changeover switch. Manual switching …
