The current work presents a unique study on the seismic performance of innovative corrugated-plate steel bridge piers. While several previous research was conducted tubes with cross sections such as rounded or semi triangular plates, structural members straight ribbed corrugation geometry under uniaxial cyclic loading remained gap. Thus, this aims to present new concept that could add promising...

We investigate the cross-sectional buckling of multi-concentric tubular nanomaterials, which are called multiwalled carbon nanotubes (MWNTs), using an analysis based on thin-shell theory. MWNTs under hydrostatic pressure experience radial buckling. As a result of this, different buckling modes are obtained depending on the inter-tube separation d as well as the number of constituent tubes N and...

Dear Sir, In the April 1950 edition of your Journal, Dr. Esplen illustrated a metal anaesthetic screen for use in thoracotomies in the lateral position. I agree that such a screen is essential to maintain a good view of the patient's airway, and more particularly to facilitate bronchoscopy without disturbing the operative field should it become necessary during operation. Such a screen can well...

Heat transfer characteristics for a laminar fully developed flow in an internally corrugated circular tube with axially uniform heat flux with peripherally uniform temperature are obtained using the method of fundamental solution and the radial basis functions. The internal shape of the tube is modelled by cosine function. The nonlinear governing equation of temperature field problem was conver...

The understanding of flow regimes in helical coils is essential the design and operation modern heat exchangers has been studied therefore intensively over past decades. However, due to subjective nature defining these regimes, previous studies showed conflicting results. scope present study perform automatic regime recognition for two-phase flows by a novel two-step machine learning approach w...

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...
