Invariant rectifying and stripping (IRS) curves are used for thermodynamic analysis of a distillation column. Thermal integration of a distillation column with the background process through side exchangers (side reboilers/condensers) is important for energy-efficient design of a distillation column. Thermal integration of a distillation column through side exchangers also improves the exergeti...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
An analysis of the effect of orientation on the heat transfer in a scaled model pin fin heat sink utilized in Light Emitting Diode (LED) lighting has been carried out using numerical method. The present study involves natural convective heat transfer that takes place in particular heat sink. A pin fin type heat sink has been studied since they are widely used in LED lighting systems which in tu...
Background & Objectives: Comfort lighting is one of the most important topics, which provides optimum physical conditions in general environment and workplaces such as hospitals. This study aimed to evaluate general, local and area artificial illumination of Hamadan city hospitals . Methods : In this descriptive-analytical study, general, local and area artificial illumina...
It is accepted that the visual comfort in schools depends on the quality of the whole visual environment. This leads to the concern upon the quality and quantity of lighting. Currently in Iran, in order to calculate energy transfer for public buildings a coefficient is usually used. This coefficient considers the rate of sunlight energy absorption in these kinds of buildings. To increase the ...
We present an experimental proof of concept of scanning thermal nanoprobes that utilize the extreme thermal conductance of carbon nanotubes (CNTs) to channel heat between the probe and the sample. The integration of CNTs into scanning thermal microscopy (SThM) overcomes the main drawbacks of standard SThM probes, where the low thermal conductance of the apex SThM probe is the main limiting fact...
This paper presents a digital holographic method to visualize and measure refractive index variations, convection currents, or thermal gradients, occurring inside transparent but strongly refracting object. The proof of principle is provided through the visualization of refractive index variation inside a lighting ampoule. Comparison with transmission and reflection holography is also provided....
