TRIBOLOGICAL BEHAVIOUR OF CROSS-SHAPED DIMPLES ON SLIDING SURFACES UNDER HYDRODYNAMIC LUBRICATION Hardik Gangadia, Saurin Sheth Acta Mechanica Et Automatica, 2024 This study reports on the tribological behaviour of sliding surfaces having cross-shaped micro-dimples on a surface. One wall is smooth and moving at a constant speed against the other fixed wall with dimples. The laser machine helps to create the desired dimples on the surface of the fixed wall. For the purpose of generating hydrodynamic pressure and tribological behaviour, the effects of cross-shaped dimples and oriented cross-shaped dimples have been compared with circular-shaped dimples. Additionally, the impact of sliding speed, dimple area density and depth on tribological behaviour was examined. The findings show that compared with a circular-shaped dimple, an unconventional cross-shaped and orientated cross-shaped dimple generates a higher net hydrodynamic pressure in the fluid domain and offers superior stability between the sliding surfaces. It has been demonstrated that geometrical factors like dimple depth and area density as well as operational factors like sliding speed have a substantial impact on the hydrodynamic average pressure and tribological behaviour of sliding surfaces. The experimental findings indicate that, for the same geometric and operating parameters, cross- and orientated cross-shaped dimples have a 20%–25% lower friction coefficient between the sliding surfaces than circular dimples. The results of the experiment support those of the analysis and CFD.
Influence of the Bowtie Shaped Dimples on the Performance of Sliding Surfaces under Hydrodynamic Lubrication Hardik Gangadia, Saurin Sheth Tribologia, 2023 It covers the tribological behaviour of sliding surfaces, one of which has bowtie-shaped micro-dimples. Against the other fixed, textured wall, one wall is smooth and moving at a constant speed. For the formation of hydrodynamic pressure and tribological behaviour, the effects of bowtie-shaped dimples and orientated bowtie-shaped dimples have been compared with circular-shaped dimples. Additionally, the impact of sliding speed, dimple area density, and dimple depth on tribological behaviour was examined. The findings show that compared to a circular-shaped dimple, an atypical bowtie-shaped and orientated bowtie-shaped dimple generates a higher net hydrodynamic pressure in the fluid domain and offers improved stability between the sliding surfaces. It has been demonstrated that geometrical factors like dimple depth and area density as well as operational factors like sliding speed have a substantial impact on the hydrodynamic average pressure and tribological behaviour of sliding surfaces. The experimental results support the conclusions from the analysis and CFD.
Gesture recognition using FPGA and OV7670 camera Deval Patel, Rohit Parmar, Arpan Desai, Saurin Sheth Proceedings of the International Conference on Inventive Systems and Control Icisc 2017, 2017 Gesture recognition has lured everyone's attention as a new generation of HCI and visual input mode. FPGA presents a better overall performance and flexibility than DSP for parallel processing and pipelined operations in order to process high resolution and high frame rate video processing. Vision-based gesture recognition technique is the best way to recognize the gesture. In gesture recognition, the image acquisition and image segmentation is there. In this paper, the image acquisition is shown and also the image segmentation techniques are discussed. In this, to capture the gesture the OV7670 CMOS camera chip sensor is used that is attached to FPGA DE-1 board. By using this gesture recognition, we can control any application in a non-tangible way.
