Kheer is a popular Indian dairy dessert prepared from concentrating milk with simultaneous cooking of rice grains. Conventional methods of preparing kheer have limited its mechanized production. Therefore, a conceptual design of continuous kheer-making machine has been prepared which among other components consists of a heating section for cooking kheer. The present study investigates the CFD ...

Nowadays all branches in modern science and industry tend to solve ever complicating problems. As the result the computational time increases considerably and it become very important to reduce the processing time and use available resources more efficiently. Parallelizing problem proves itself as efficient way to overcome the described problem. In the poster we compare different methods of ...

This study is to investigate the velocity pattern and the velocity magnitude of the cuttings that is being processed in the process mill as a result of the rotating hammers. The process mill consists of a horizontal cylindrical shell equipped with renewable liners and rotating hammers for milling of drill cuttings. An F.E model of the process mill was constructed using dimensions similar to ...

The most common way to exchange heat with the bedrock in Ground Source Heat Pump (GSHP) applications is circulating a fluid through a U-formed closed loop in vertical boreholes drilled several tenths of meters into the ground. This study presents and compares the results of eight cross sectional U-pipe Borehole Heat Exchanger configurations. Values from recent experimental temperature ...

In this article we present Simulations results of an evaporation reactor for optical layer applications. The thermal simulation concern the source of the evaporated material. An experimental problem is ralated to the shape of the material powder surface: due to the evaporation rate, the surface don\'t keep his flat initial shape and this has a strong effect on the local evaporation rate. In ...

A multiphase porous media model involving heat and mass transfer within a potato chip was implemented in COMSOL 3.5a. The diffusive flux in oil and liquid water was modeled from capillary driven flow while the gas phase was modeled using binary diffusion. A non-equilibrium water evaporation rate was used and Darcy's law for the momentum equation to solve for the convection of each ...

The design of a RFID-enabled temperature sensor is described in this paper. In this sensor, a change in temperature causes structural beams to bend, which results in a proportional displacement of the plates of the capacitor. Plates\' displacement results, in turn, in changing the value of its capacitance. The capacitor of the sensor is coupled to the LC resonant network of a passive RFID tag. ...

In this paper a methodology for calculating the infrared signature of complex objects is presented. The transient thermal analysis allows us to evaluate the temperature distribution on the investigated object, pointing out which parts tend to be warmer. These temperature values are handled in the post processing phase in order to evaluate the zero range radiance distribution and the radiance of ...

The efficiency of borehole heat exchangers (BHEs) for geothermal purposes depends not only on material properties but also on their geometrical design. These days most used design consists of two parallel arranged U-shaped pipes which are embedded in a high-conductive shell filling out the borehole. Another common design is a pipe inside of another pipe, with fluid flowing down inside and up ...

This paper describes a model of self-ventilated generator cooling on a 170 tons off-road mine dump truck. Considering the space restrictions of mine dump truck, the cooling systems for the generator and the in-wheel motors of the rear axle share one air inlet duct. With the action of generator fan and rear duct fan, cooling air from the inlet duct will be divided into two parts to cool the ...
