An electron beam evaporator has been assembled, tested and used for deposition of thin nickel films. Flux and deposition rates has been measured with an oscillating quartz crystal monitor (QCM), an ion sensor wire, and visible deposition on a mirror on front of the evaporator. A thin nickel rod of 2 mm diameter was found to improve the pressure in comparison to a 6-mm nickel rod. The flux was t...

Heat pipe is a device that transports heat with minimal temperature drop using the latent heat of fluid in a closed container. In vertical type named as thermosyphon (Wickless), capillary action is replaced by the gravitational force, this condenser is placed above evaporator. In this paper, to investigate the effect of inlet air temperature and the air mass flow rate was studied. The temperatu...

The last stage in the design process for a chemical product is its manufacture, where the purification has an important role. Short-path evaporation is a safe method suitable for separation and purification of thermally unstable materials. In this work the process modelling and a systematic strategy of solution is presented for a short-path evaporator to obtain the desired product specification...

ing characteristics could be investigated. Finally the pilot plant A single tube plant Kestner evaporator'was set up at was run under 1st effect conditions in order that a comparison Illovo to investigate heat transfer characteristics when could be made with industrial 1st effect evaporators (both simulating different evaporator Tests carried out have Roberts and Kestner). This particular trial...

This paper describes a multi-evaporator vapor compression model capable of simulating the dynamic behaviour of transport refrigeration systems. A discrete multi-zone control volume approach is utilised for modelling the condenser and evaporators. All other major refrigeration components including compressor, expansion valves, receiver, pressure-regulating valves are modeled using time-dependent...

Evaporator merupakan salah satu alat utama di unit kilang PPSDM Migas Cepu yang sudah cukup lama digunakan sehingga perlu dilakukan perhitungan efisiensi evaporator. Perhitungan untuk mengetahui kelayakan evaporator tersebut proses pengolahan minyak mentah Cepu. berdasarkan data dari yaitu kondisi evaporator, densitas tiap komponen, massa dan distilasi ASTM (American Society for Testing Materia...
