Wort boiling is the most energy intensive stage in brewing process. Novel wort systems have been explored to reduce primary consumption and improve quality beer flavor stability. Low thermal stress proposed for boiling, but content of dimethyl sulphide (DMS) may exceed required product threshold. A single spinning cone evaporator (SCE) enhance separation DMS minimise wortboiling. The performanc...

Anxiety is feeling of danger in a person who is threatening with something. Nowadays, anxiety is increased in different populations and, thus it is became an important problem in many countries. Melissa officinalis (Melissa) and Valeriana officinalis (Valerian) are two medicinal plants. These two plants are traditionally used as sedative herbal drugs and new studies on their pharmacological act...

In this paper, mini-channel type evaporator which is new in mobile air conditioning (MAC) or automotive air conditioning (AAC) systems is thermally modeled. The performance of mini-channel evaporator is also compared with the laminated evaporator which is being currently used in automotive industries. The mini-channel evaporator was constructed of two rows of parallel flow mini-channel tubes...

A comparative numerical study is employed to investigate the heat and mass transfer between air and falling film desiccant in parallel and counter flow configurations. Nanoparticles suspensions are added to the falling film desiccant to study heat and mass transfer enhancements. The numerical results show that the parallel flow channel provides better dehumidification and cooling processes of t...

Flow visualization with high-speed video of evaporating water films falling over flat horizontal tubes, representative of the external surfaces of microchannel tubes, is presented. Experiments were conducted with 1.4 mm thick and 27 mm tall tubes over a film Reynolds number range of 23 < Re < 126. In addition to a qualitative description of the flow mechanisms, this work quantifies key droplet ...

A thermal stress range analysis of tungsten-rhenium thin film thermocouples based on ceramic substrates is presented to analyze the falling off and breakage problems caused by the mismatch of the thermal stresses in thin film thermocouples (TFTCs) and substrate, and nano-indentation experiments are done to measure and calculate the film stress to compare with the simulation results. Optimal des...

Painters reproduce the appearances they see, or visualize. The entire human visual system is the first part of that process, providing extensive spatial processing. Painters have used spatial techniques since the Renaissance to render HDR scenes. Silver halide photography responds to the light falling on single film pixels. Film can only mimic the retinal response of the cones at the start of t...

Three evaporators are used to reduce the volume of waste in the waste tank farm at the Savannah River Site (SRS). Evaporators are crucial operation in the SRS waste processing and management system. Using the Aspen Custom Modeler (ACM) software package marketed by Aspen Technology, Inc., the evaporator dynamic flowsheet models have been constructed to simulate the behavior of the evaporator sy...

Experimental investigation on the performance of dual-evaporator refrigeration system with an ejector has been carried out In this study, HFC-134a is chosen as a working fluid. Test setup is composed of compressor, condenser, expansion valves, two evaporators, and ejector which is installed between two evaporators. The condenser and two evaporators are made as concentric counter-flow type heat ...

The performance of various working fluids for automotive air conditioning was calculated using a computer simulation. The model solves for the steady-state performance of a system that consists of a compressor, condenser, expansion valve, and evaporator, either with or without a liquid line/suction l i e interchanger. Condenser and evaporator performance is calculated based of user-defined valu...
