Hydrocooling is the process by which warm produce is chilled with water. The chilling of warm produce generates a negative pressure differential between the produce (warm) and (cold) water due to the condensation of water vapor inside the produce which forms a vacuum and can pull in contaminated water through an opening. A porous media based model of water infiltration was developed using a ...

Localized convection heat and mass transfer can be intensified and optimized by providing exposure to electromagnetic energy. Conjugate heat and mass transfer are configured by solving the momentum, heat and mass transfer simultaneously in both solid (substrate, comprising of a two-phase chemical species) and fluid (auxiliary air) phases. In this way the heat and mass fluxes vary seamlessly ...

Targeted drug delivery systems have been wildly studied in cancer therapy due to the toxicity of most of chemotherapeutic drugs. Nanoparticles can be attached to the small molecules of the drugs and serve as drug carriers to deliver the drug molecules into the area of interest. In this research, polymeric microspheres containing biodegradable poly(D, L-lactide-co-glycolide) (PLGA), magnetic ...

Metal foams are interesting materials with many potential applications. Foamed metals or alloys include gas voids in the material structure and therefore the density is introduced as a new variable, with the real possibility to modify ad hoc their physical properties. In the indirect foaming process carried out in a furnace, simultaneous mass, momentum and energy transfer between three phases, ...

Low temperature fuel cells require hydrogen of high purity for electricity production to avoid catalyst poisoning. To purify hydrogenrich flue gases from hydrocarbon steam reforming membrane shift reactors with a metal membranes may be utilized. A model of a tubular membrane shift reactor with a hydrogenseparating palladium membrane is modeled in the COMSOL Multiphysics® Chemical Engineering ...

Dilution’s issue during dry machining have raised the interest’s environmental researchers and engineers. In fact, the sampling of dust emitted during dry machining was a serious problem for air quality evaluation at the workplace. Furthermore, the best sampling of fine and ultrafine particles produced during material cutting, passed through the dilution of high particle concentration (number, ...

Implant devices are assistive devices surgically placed in the human body to restore the functionality of organs and tissues. Metallic implants are often used for load bearing applications including the hip and knee joints. To allow maximum flexibility during surgery for surgeons to pick and choose different combinations of parts (say, head, neck and stem, in the case of total hip replacement), ...

Diabetes mellitus affects 387 million people across the world according to the latest estimates of International Diabetes Foundation. Insulin is one of the major drugs required to keep the glucose level within desired limits in a diabetic patient. Insulin is generally administered to a patient as a subcutaneous injection and consists of two forms namely, basal and bolus. The basal dosage is ...

In the field of chemical reaction engineering chemical kinetics and fluid dynamics are described by various mathematical approaches. Such tools help to shorten the time-to-market of novel products and processes. Thanks to the continuously improving computation power, it is possible to consider the kinetics of chemical reactions as source terms in the Navier-Stokes equations. Even a coupling with ...
TRISO（TRistructure ISOtropic）燃料颗粒不仅是在役高温气冷堆燃料元件的核心部件，同时也是下一代用于水冷反应堆的全陶瓷微密封（FCM）耐事故燃料（ATF）元件的关键组成部分。TRISO燃料颗粒由内核部分和包覆层两部分组成，其中内核部分包括球形UO2或UN燃料核芯和包围核芯的疏松热解碳缓冲层，包覆层由内向外依次为内致密热解碳层（IPyC层）、碳化硅层（SiC层）和外致密热解碳层（OPyC层）。基于COMSOL Multiphysics®多物理场耦合有限元软件开发了TRISO燃料颗粒的三维热学-力学-裂变产物扩散耦合分析模型，详细考虑了材料物性参数随温度、快中子注量、各向异性系数和燃耗等因素的变化，热膨胀，燃料核芯的密实和肿胀，Buffer层、IPyC层和OPyC层辐照变形，SiC层、IPyC层和OPyC层辐照蠕变，Buffer层与IPyC层之间的间隙导热 ...
