Injection Strategies

Effect of spray/wall interaction in a rapid compression and expansion machine on mixture formation, ignition location, and soot generation was investigated. A two-dimensional piston cavity designed as the cross section of a reentrant piston was utilized to observe the spray and combustion process from the lateral side. The experiment was conducted at 120 MPa injection pressure under single and split injection strategies with an ambient gas of 15% O2 concentration. A shadow methodology was applied to investigate the interaction between the fuel spray and the piston cavity. Combined with the natural flame luminosity captured by a high-speed color video camera, the behaviors of the impinging spray and the combustion process were studied. The combustion characteristics of the in-cylinder pressure, heat release and combustion phase were recorded and analyzed simultaneously. The results showed that the split injection strategies effectively softened the heat release trace and promoted the onset of the main combustion. The cool-flame phenomenon was captured by using the high-speed color video camera, and the intense ignition was observed when the pilot spray was controlled to impinge on the lower lip of the piston rim. Moreover, results also showed that further extending the mixing process of the pilot spray is inclined to form a homogeneous mixture which was beneficial for the promotion of low-temperature combustion and the reduction of soot generation. This research provides a detailed investigation on the spray and combustion process and it highlights the significant effect of spray/wall interaction on the subsequent combustion process.

Purpose of the Study: This study aims to describe the muscle activity and its role in the upper extremity in Badminton Strokes and also investigates the Kinematics differences of Badminton forehand overhead shot, i.e., precise, smash and drop in wrist joint, elbow joint, and shoulder Joint from a biomechanics perspective. Methodology: Total [n=10] numbers of male badminton players were randomly selected from the badminton match practice group of L.N.I.P.E. Gwalior, Madhya Pradesh, India. The match practice group consisted of (n=78) players who at least participated in Inter-University badminton competition, and their age ranges from 17-25 years of old. Go Pro HERO 7, 2D camera was used. A video camera was mounted on a tripod at a height of 1.05 meters from the ground. 2D data of wrist joint, elbow joint, and shoulder joint were put in Kinovea 0.8.27 software. One way ANOVA was used. Principal Findings: The results of the finding demonstrate that Brain vibrations, paradoxically, are critical to the stability of movement and high performance. There are significant muscle activity and kinematics differences among forehand clear, forehand smash and forehand drop-in shoulder joint angle, elbow joint angle, and wrist joint angle. Applications of this Study: The Study may use by the badminton Players as well as coaches for the successful execution of badminton Skill. This study will provide the mechanical area of movement of badminton Players. The same kind of study may use in other games. Novelty/Originality of this Study: The Study explores the mechanical advantages of badminton forehand overhead Skill. It will give the reader new ideas to think of a similar kind of study in different games.

An augmenter viewing system employing a coherent fiber-optic array was developed for use in jet engine testing applications at AEDC. Real-time viewing of the test article afterburner was obtained in a severe environment under high temperature and vibration levels. The optical system consisted of a conventional front-end lens assembly coupled with the fiber-optic array, and a solid-state color video camera mounted inside the test cell. The advantages and problems associated with a fiber-optics-based viewing system will be discussed in comparison with more conventional viewing techniques for this application.
