Heat generation during oblique particle impact
نویسندگان
چکیده
Granular flows are characterised by particle interactions that involve sliding and collisions. In such events, heat is generated from friction plastic deformation. Despite the importance of self-heating mechanisms, our understanding fundamental principles generation dissipation still limited. This work explores this problem at level for oblique impacts between a spherical rigid substrate. first part, theoretical models finite element method (FEM) model used to predict amount contact temperatures various impact angles. The FEM in good agreement all cases considered. A parametric study influence on temperature distributions also carried out. It shown profiles dependent not only but material’s thermal properties, as conductivity specific head capacity. Apart insight into during impacts, identifies simple solutions can be other numerical tools, discrete methods, studying problems bulk granular flows.

Heat transfer during impact
The amount of heat transferred by conduction during the impact of a spherical particle with a surface depends on the thermophysical and mechanical properties of the two colliding media. Other factors, such as the surface properties (e.g. roughness, contamination, stress state, radius of curvature) and the velocity and direction of the impact, also influence the heat transfer. The available theo...
متن کاملAdhesive Contact During the Oblique Impact of Elastic Spheres
An integral representation is developed for the distribution of tangential traction duringadhesive contact between obliquely loaded elastic spheres of similar materials. It is shown thatadhesive conditions arise at the beginning of an impact between two spheres at low angles ofincidence or after an initial period of gross slip for larger angles.A differential equation is dev...

در سال های اخیر به دلیل افزایش دمای متوسط کره زمین، بشر به دنبال روش های جایگزین برای تامین توان الکتریکی مورد نیاز خود بوده و همچنین در اکثر نقاط جهان سوزاندن سوخت های فسیلی در نیروگاه های حرارتی به عنوان مهم ترین روش تولید توان الکتریکی مطرح بوده است. به دلیل توجه به مسایل زیست محیطی، استفاده از منابع انرژی تجدید پذیر در سال های اخیر شدت یافته است. نیروگاه های بادی به عنوان یک منبع تولید توان...
15 صفحه اولThe Deep Impact oblique impact cratering experiment
The Deep Impact probe collided with 9P Tempel 1 at an angle of about 30◦ from the horizontal. This impact angle produced an evolving ejecta flow field very similar to much smaller scale oblique-impact experiments in porous particulate targets in the laboratory. Similar features and phenomena include a decoupled vapor/dust plume at the earliest times, a pronounced downrange bias of the ejecta, a...
