Heat exchangers are the critical components of refrigeration and liquefaction processes. Selection of appropriate operational conditions for cryogenic recuperative heat exchanger and expansion valve operating in Joule-Thomson cooling system results in improving the performance and efficiency. In the current study, a straightforward procedure is introduced to design an efficient Joule-Thomson co...

simulation of rough rice drying is one of the proper methods for predicting moisture distribution in the product, and throughout the process of drying. the drying process must be well understood and controlled so that design guidelines which reduce or minimize drying damage to rough rice can be established and improved. therefore, an accurate understanding and description of the drying mechanis...

the objective of this work was to develop a new design of an intake manifold through a 1d simulation. it is quite familiar that a duly designed intake manifold is essential for the optimal performance of an internal combustion engine. air flow inside the intake manifold is one of the important factors, which governs the engine performance and emissions. hence the flow phenomenon inside the inta...

System-level design is characterized by a behavioral specification and heterogeneous hardware/software implementations. Exploring the design space is essential for good design. Specifying and managing complex design flows, tracking dependencies and tool invocations, and maintaining consistency of design data and flows are key issues that enable efficient design space exploration. In order to ma...

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 de...

the present paper describes the designing of a thermally and economically optimum mechanical draft counter-flow wet cooling tower. the design model allows the use of a variety of packing materials in the cooling tower toward optimizing heat transfer. once the optimum packing type is chosen, a compact cooling tower with low fan power consumption is modelled within the known design variables. mor...
