Accurate metrology of radiotherapeutic absorbed dose to water requires assessing the radiation induced temperature change. The most direct method for doing this is water calorimetry, for which the established technique involves the use of slender thermistor probes that are sealed within a glass vessel containing high-purity water. The probes and vessel perturb the radiation field, via ...

Auxiliary Power Units can play an important role in reducing vehicle emissions, especially in diesel and kerosene driven vehicles. In conventional vehicles the electricity supply comes from a generator that is directly coupled to the propulsion engine. New generation of fuel cell APUs exclusively use Solid Oxide Fuel Cells with some developments in high temperature polymer electrolyte membranes ...

Corrugated board is produced on a machine where the corrugated medium is glued between two flat paper surfaces, the liners. The board is cut into sheets and stored in a stack until suitable moisture content has been reached. The sheets are then cut and creased into blanks for the production of boxes and other products. If the moisture content is too high, there is a risk for cutting problems in ...

Most technical systems become smart over time, therefore those systems will have improved safety and comfort functions. An example is a new development by Westfalia-Automotive. A new generation of smart tow bars, equipped with a sensor system, including distance sensors, is able to inform the driver of a car with a connected trailer about vertical and trailing loads. This helps to ensure a ...

A two dimensional instationary analysis of the conjugate optical-thermal fields induced in a multilayer thin film structure on a glass substrate by a moving Gaussian laser source is carried out numerically in order to compare back and front laser treatment processes. COMSOL Multiphysics 3.4 code has been adopted to solve the combined thermal and electromagnetic problem in order to compare the ...

Pyrochemical process based on molten salt electrorefining is ideally suited for reprocessing spent metallic fuels from Fast Breeder Reactors. In this work, a heat transfer analysis of the Electrorefiner cell was conducted to develop a basic tool for designing of the engineering–scale Electrorefiner. The focus of this work is to find out steady state temperature profiles of cover gas and molten ...

Catalytic micro-combustor represents an exciting area of research for portable power generation. Extensive research is being currently conducted on the design of the reactor and catalyst selection . However another critical element of the design will be a recuperator to minimize losses and provide energy at a more uniform temperature. The mini-recuperator must be both compact and highly ...
