Modified Design Improvement Study and Optimization of a intake Manifold to Obtain Unequal Distribution of Velocity for Optimal Diesel Engine Performance
Abstract: Geometrical design of intake manifold has been found very significant for the better performance of an I.C. Engine. It becomes less effective at the intake manifold's runner's outlets due to an uneven flow distribution of the intake air. With an increase in velocity at the distribution channels, the presented study seeks to make this uneven velocity distribution nearly equal without requiring any additional significant changes to the entrance manifold's construction. …

Numerical Study on the Effect of Ball Baffles in Reducing Sloshing Loads in Ship Tanks
Abstract: Sloshing is the free surface motion of a liquid in a partially filled container under periodic motion. Liquid sloshing will result in dynamic pressure on the walls of the container causing large deformations to the tank as well as the supporting structures and carrier. This dynamic pressure on the tank walls due to slosh waves are conventionally mitigated in the tanks of very large crude oil carrier (VLCC) ships by …

Experimental Test Results on the Effect of Ultrasonic Waves on Defects in Car Bearings: The Effect of Defect Size
Abstract: To check for defects in car bearings, they are identified and measured by sound waves that are affected by the defect. Based on sound, it is called ultrasound technology because it uses high frequencies. High frequencies are the basis of ultrasound. Two features are useful for low-speed cars, which by definition usually have poor signal tolerance. High frequencies are sensitive to the effects of sound waves. In addition, the ultrasound …
