    EXPERIMENTAL INVESTIGATION OF FLOW OVER A CYLINDER AND WING WITH VORTEX GENERATORS USING PIV
    (I.O.E, 2024-03) Devkota, Kshitish Chandra; Mishra, Praphul; Adhikari, Sandip; Banjade, Shreeju; Darlami, Kamal
    Particle Image Velocimetry (PIV) is a non intrusive flow measurement technique used for qualitative and quantitative analysis of flow dynamics. In this study, PIV is employed to investigate flow behaviour around a circular cylinder and a wing, with and without vortex generators (VGs). The research pursues dual objectives: to characterize the PIV setup using the Strouhal number (a dimensionless parameter) and to analyze flow characteristics, particularly focusing on stall conditions. Systematically, a linear actuation mechanism is developed to facilitate experimentation on both models. Image processing, conducted in PIVLab alongside the development of necessary code written in MATLAB, are incorporated for detailed analysis, with time-dependent signals transformed into the frequency domain using Fast Fourier Transform (FFT) for comprehensive evaluation. The characterization of existing PIV setup was done through three sets of experimental data using strouhal number for analysis of flow around circular cylinder. The strouhal number obtained are 0.1897, 0.1952 and 0.1952 with 3.6777 %, 0.9137 % and 0.9137 % errors respectively. Velocity field and vorticity contours were studied for the aerodynamic flow analysis of baseline wing and wing with VG at the 15 degree angle of attack. The obtained Strouhal number for wing and wing with VGs are 0.1381 and 0.1571 respectively. The comparison concludes that vortex generators energize the boundary layer above the wing and delay the flow separation

    Land and Identity in John Steinbeck's Of Mice and Men
    (Department of English, 2015) Adhikari, Sandip
    The research entitled land and identity in John Steinbeck’s of mice and men deals about the life of migrant ranch worker, the ranch worker migrates from one place to another in search of the job in the great depression era, how the land become the bonding tie between the migrant ranch worker and their existence , how land is the milestone for the foundation of the identity, dignity of the ranch worker is being reflected in the work, how the land plays the major role for the survival in the ranch workers how land creates the feeling of ownness and belongness among the migrant ranch worker is depicted in the work . Since land is the root, the work focuses on the close affirmitiy between the land and the migrant ranch workers it deals how hard the migrants struggle for the possessing of the land. Basically the research is concerned with how the land is the major factor for the discovery of their identity, dignity and existence, after the meticulous study on the novel in the light of various ecocritics .
