چکیده
In this research scotch pine (Pinus sylvestris L.), Eastern beech (Fagus orientelis L.), oak (Quercus petraea L.) samples have been covered with polyurethane, acrylic, cellulosic varnish. In order to determine the physical changes which occurred on varnish layers caused by steam and wet heat, the samples were exposed to TS 4982 EN 12721 wet heat and TS EN 438-2 steam. According the results, the most strength to steam was observed in the polyurethane varnish applied on beech material. The least strength was observed on cellulosic varnish applied on beech. The most strength to wet heat was observed on acrylic varnish applied on beech and oak. The least strength was determined on cellulosic varnish applied on beech and oak. As a result, in furniture which will be used in the environments containing wet heat and steam, the use of beech and oak as the wooden material and polyurethane and acrylic varnish as the protector layer can be recommended.

Water thickness effect on the fin efficiency and heat transfer for partially wet-surface heat exchanger
Heat and mass transfer, in this paper, is considered in one-row heat exchanger, that fins are hotter than air flow and water is added to fins. Related governing equations are derived by analyzing a two-dimension model in a unique cell of a heat exchange. These equations are numerically solved by finite difference method. Heat transfer and efficiency under partially wet surface are calculated by...
متن کاملHydrogeochemistry of hydrothermal waters from Salams magma chamber: Case study of Isti Su hot spring, NW of Iran
The Isti Su hot spring is located in southeast of Salmas, in Western Azerbaijan, Iran. The area is a small part of Sanandaj-Sirjan geological zone which hosts many hot springs. The magma chamber of Salmas region is the main heat source of the hot springs in Isti Su area. Abundant rainfall and relatively long duration of snowfall as well as several deep faults in the area create the best conditi...

Introduction: This study was designed with the main purpose of examining the compatibility of the two indicators of wet bulb globe temperature (WBGT) and predicted thermal strain (PHS) in assessing the environmental conditions and the heat load imposed on the subjects. Method: In this cross-sectional study, 163 bakers were included in the study. Thermal stress was determined using the WBGT and...
متن کاملTechno-Economic Assessment of Different Inlet Air Cooling Systems in Warm Dry & Wet Climate Stations
Performance of a gas turbine mainly depends on the inlet air temperature. The power output of a gas turbine depends on the flow of mass through it. This is precisely the reason why on hot days, when air is less dense, power output falls. The objective here is to assess the advanced systems applied in reducing the gas turbine intake air temperature and examine the merits from integration of the ...
متن کاملAn Investigation into the Effect of Hydrotalcite Calcination Temperature on the Catalytic Performance of Mesoporous Ni-MgO-Al2O3 Catalyst in the Combined Steam and Dry Reforming of Methane
Several mesoporous nickel-based catalysts with MgO-Al2O3 as the catalyst support were prepared using a co-precipitation method at a constant pH. The supports were prepared from the decomposition of an Mg-Al hydrotalcite-like structure which had already been prepared with Mg/Al=1. Prior to impregnating 10 wt.% nickel on the supports, the precursor was decomposed at several ...
