Hydrogen peroxide (H2O2) vapor is a preferred medium of sterilization in different fields of industry. Among the fact that it dissociates to oxygen and water (environmentally-friendly), H2O2 vapor possesses strong mircobicidal and sporicidal characteristics. As such, the use of H2O2 vapor as a sterilant has continuously increased in different fields of industry, like in medicine, pharma and food ...

The idea of application as a hearing device based on a parasitoid fly, Ormia ochracea has been studied extensively recently. This paper addresses another possible application as an underwater directional sensor. In order to study the feasibility of the application, it is necessary to investigate the feasibility of the underwater application of the directional sensor based on the hearing ...

This paper compares the efficiency of a vertical solar dryer vis-à-vis the traditional drying method by the means of a computer simulation. The said program considers geometric, thermal and mechanical effects so as to simulate heat transfer via conduction, convection and radiation. We later ran additional tests with simulated data on the greenhouses(traditional method) so as to compare the ...

In this work we consider a 1-D mathematical model that describes a heating problem combined with electrical current flows in a body which may undergo a phase change as a result of the heat generated by the current, so-called Joule heating. The model consists of a system of nonlinear partial differential equations with quadratic growth in the gradient. Joule heating is generated by the resistance ...

The estimation of the soil saturated hydraulic conductivity (Ks) is crucial in understanding water flow and transport of contaminants. There are many hydrological techniques available in determining this parameter (constant head method, in-situ soil analysis, etc...). While these techniques can provide quality data points, they are often limited by sparse data sampling and scale. Therefore ...

We have developed single leg model using COMSOL Multiphysics® software to compute Φ of TE materials without using conventional ZT parameters. The Φ were calculated using parametric programming in PDE by using special probe to capture change in power (∆P), ΔT, and area (A), thus (Φ = ∆P/A*ΔT 2). The obtained results showed that the TE material with highest Φ when the temperatures are between 375 ...

Recently, increasing availability of natural gas, due to the shale gas, raises the attention to the conversion of methane. Methanol-to-Hydrocarbons reaction (MTH) plays an important role in this route where methanol synthesized through syngas is converted into hydrocarbons, such as Gasoline. In this study heat and mass transfer for MTH reaction over ZSM-5 as catalyst for an specific microreactor ...

Injection conditions of CO2 at the wellhead may play a major role on the flow behavior through the wellbore. The density and the injection rate reached at the bottomhole are key factors affecting the performance and efficiency of CO2 geological storage. In this work, a model of non-isothermal flow of CO2 in injection wells is developed using COMSOL Multiphysics® software and used to assess ...
