mixed convection is a fundamentally significant heat transfer mechanism that occurs in selection industrial and technological applications. in this study, first the laminar mixed convection inside rectangular enclosure with moving wall and aspect ratio=10 is modeled and then the results are compared with other investigate. after showing varity of results, the investigation is continued with tur...

Many studies have found that the perceived authenticity of cultural and religious events affects event satisfaction and loyalty. Little is currently known about how perceived authenticity is affected by the facilities, such as food and the availability of information, which are independent determinants of satisfaction and loyalty. This study aims to examine the antecedents of event loyalty. Que...

در محیط محاسبات فراگیر، تمام وسیله هایی که قصد برقراری ارتباط با یکدیگر را دارند با رویدادها سر و کار دارند. به همین دلیل، کشف سرویس ها و مدیریت رویدادها در این محیط از حساسیت و پیچیدگی محسوسی برخوردار است. با توجه به اهمیت موضوع، هدف این رساله ارائه ی شیوه ایست که با استفاده از پایگاه داده ی فعال و به کارگیری قوانین eca (event, condition, action)، پیچیدگی رویدادهای بین وسیله ها را کاهش داده ...

A convenient method to create vortices in meta-stable vortex-free superflow of 3 He-B is to irradiate with thermal neutrons. The vortices are then formed in a rapid non-equilibrium process with very distinctive characteristics. Two models were suggested to explain the phenomenon. One is based on the Kibble-Zurek mechanism of defect formation in a quench-cooled second order phase transition. The...

The fusion event in inertial fusion energy (IFE) reactors creates neutrons, photons and charged particles that can damage the chamber first walls. The Prometheus design study used a high-speed thin film of molten lead injected tangential to the wall to protect the upper endcap of the reactor chamber from damaging x-rays and target debris (1,2). To assure full chamber coverage, the film must rem...

We present 50 individual measurements of the gas temperature and turbulent velocity in the local interstellar medium (LISM) within 100 pc. By comparing the absorption line widths of many ions with different atomic masses, we can satisfactorily discriminate between the two dominant broadening mechanisms, thermal broadening and macroscopic nonthermal, or turbulent, broadening. We find that the su...

A new finite volume algorithm has been developed to solve a variety of flows by using large eddy simulation and direct numerical simulation. This finite volume algorithm was developed using a dual time stepping approach with a preconditioning technique and a new factorization implementation. The method takes the advantage of pressure-based and density-based meth­ ods. Thus, it provides an effic...

We measure the turbulent diffusion coefficient of dust grains embedded in magnetorotational turbulence in a protoplanetary disc directly from numerical simulations and compare it to the turbulent viscosity of the flow. The simulations are done in a local coordinate frame comoving with the gas in Keplerian rotation. Periodic boundary conditions are used in all directions, and vertical gravity is...
