This paper presents the numerical simulation model for radiocesium leaching and transporting behavior in municipal solid waste (MSW) landfill and discusses on the design for the required geometry and properties of the impermeable final cover and the soil sorption layer, which work for containment of hazardous waste such as radiocesium-contaminated MSW generated by Fukushima Daiichi nuclear ...

In our study of chaotic mixing, 3D velocity measurements (u,v,w) are required for evaluation of a micro mixer using a mix-prediction algorithm. The hybrid approach presented here combines 2D measurements, an imperfect numerical model, and appropriate fitting parameters. Because our purpose is a measurement, rather than development of a physically accurate and predictive model, it not necessary ...

Introduction: Chronic arterial hypertension (HTN) is a pathological condition characterized by prolonged high level of arterial blood pressure causing major damages to several human body apparata. Renal sympathetic denervation (RDN) has been found to effectively reduce systemic blood pressure. Metallic electrodes can be placed on an endovascular device connected to external radio frequency (RF) ...

Introduction In order to understand the detection mechanism of the PZT based nondestructive testing (NDT) technology for interface debonding of CFSTs, numerical simulation on a multi-physical model composed of surface-mounted PZT patches and CFST structural member is established in COMSOL Multiphysics®. The stress propagation process and the electrical signal output of an embedded PZT patch as ...

Microreactors are important alternative to conventional reactors in chemistry, chemical, pharmaceutical and semiconductor industries due to their operation characteristics such as increased mass and heat transfer, uniform flow, safety, high throughput through array configurations, smaller plant size and lower cost of production. Models for such reactors need to be able to describe both the ...

Kennedy Space Center is leading research work on lunar O2 generation via electrolytic reduction of regolith. The metal oxide present in regolith is dissociated into oxygen anions and metal cations leading to the generation of gaseous oxygen at the anode and liquid metal at the cathode. The authors have developed a 3D model using a rigorous approach to not only study the effect of Joule heating ...

This study is a part of the Silent Wall ANR project, to which the Center of Mathematical Morphology is associated. Its main objective is to build an acoustical and thermal insulating system for buildings, composed of fibrous materials. The material is composed of two phases: the fibrous network and the air surrounding it. At the microscopic scale the absorption of the acoustic wave is mainly ...

A resonant MEMS sensor for viscosity and mass density measurements of liquids was modeled. The device is based on Lorentz-force excitation and features an integrated piezoresistive readout. The core sensing element is a rectangular vibrating plate suspended by four beam springs. The liquid surrounding the plate influences the resonant behavior of the system. Thus, evaluating the properties of ...

Regenerative heat exchangers (RHX) find widespread applications in liquid food or pharmaceutical processing as well as in reaction engineering. Whereas \"large\" RHX systems have been in use for a long time, their smaller micro-channel counterparts are a more recent area of interest. Here, we describe the design and development of a novel micro-channel counter-current regenerative heat ...
