Experimental and numerical study of heat transfer through a synchronous belt transmission type AT10.

Appl Therm Eng 2017 Dec;127:705-717

ETAP Laboratory - University Abou bekr Belkaid, Tlemcen, Algeria.

In most industrial applications, the re-use of belts in power transmissions continues to increase and invade the market especially in automobiles where various types of belts are used. For this purpose, the belt manufacturers are aware of the importance and the valuable advantages of this transmission member and put all their efforts to develop and improve its geometrical and mechanical characteristics in order to achieve an optimal service life. Indeed, this article is devoted to an experimental and numerical thermal study of a toothed belt transmission type AT10. Read More

Modeling carbon monoxide spread in underground mine fires.

Appl Therm Eng 2016 May;100:1319-1326

Office of Mine Safety and Health Research, National Institute for Occupational Safety and Health, 626 Cochrans Mill Road, Pittsburgh, PA 15236, USA.

Carbon monoxide (CO) poisoning is a leading cause of mine fire fatalities in underground mines. To reduce the hazard of CO poisoning in underground mines, it is important to accurately predict the spread of CO in underground mine entries when a fire occurs. This paper presents a study on modeling CO spread in underground mine fires using both the Fire Dynamics Simulator (FDS) and the MFIRE programs. Read More

Effect of Common Faults on the Performance of Different Types of Vapor Compression Systems.

Appl Therm Eng 2016 Apr;98:61-72

HVAC&R Equipment Performance Group, National Institute of Standards and Technology, 100 Bureau Drive, MS 8631, Gaithersburg, MD 20899, USA.

The effect of faults on the cooling capacity, coefficient of performance, and sensible heat ratio, was analyzed and compared for five split and rooftop systems, which use different types of expansion devices, compressors and refrigerants. The study applied multivariable polynomial and normalized performance models, which were developed for the studied systems for both fault-free and faulty conditions based on measurements obtained in a laboratory under controlled conditions. The analysis indicated differences in responses and trends between the studied systems, which underscores the challenge to devise a universal FDD algorithm for all vapor compression systems and the difficulty to develop a methodology for rating the performance of different FDD algorithms.

Energy Use Consequences of Ventilating a Net-Zero Energy House.

Appl Therm Eng 2016 Mar;96:151-160

HVAC&R Equipment Performance Group, Energy and Environment Division, National Institute of Standards and Technology, 100 Bureau Drive, MS 8633, Gaithersburg, MD 20899, USA.

A Net-Zero Energy Residential Test Facility (NZERTF) has been constructed at the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland to demonstrate that a home similar in size, aesthetics, and amenities to those in the surrounding communities can achieve net-zero energy use over the course of a year while meeting the average electricity and water use needs of a family of four in the United States. The facility incorporates renewable energy and energy efficient technologies, including an air-to-air heat pump system, a solar photovoltaic system, a solar thermal domestic hot water system, and a heat recovery ventilation system sized to meet American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE) Standard 62.2-2010 ventilation requirements.

A two-temperature model for selective photothermolysis laser treatment of port wine stains.

Appl Therm Eng 2013 Sep;59(1-2):41-51

Laser Treatment Center, Department of Dermatology, Medical School, Xi'an Jiaotong University, Xi'an, Shaanxi, 710049, China.

Selective photothermolysis is the basic principle for laser treatment of vascular malformations such as port wine stain birthmarks (PWS). During cutaneous laser surgery, blood inside blood vessels is heated due to selective absorption of laser energy, while the surrounding normal tissue is spared. As a result, the blood and the surrounding tissue experience a local thermodynamic non-equilibrium condition. Read More
