Abstract:
The fire resistant behavior of web-slotted cold-formed channel columns with non-uniform temperature distributions was investigated extensively by use of the finite element method in this article. The failure mode of the web-slotted column with non-uniform temperature distributions is very complex with the interaction of the local buckling, the distortional buckling and the global flexural buckling. The ultimate strengths of members with non-uniform temperature distributions are higher than that with uniform temperature distributions of the same highest temperature. In addition the analysis res

Abstract:
Thin-walled cold-formed steel (CFS) has exhibited inherent structural and architectural advantages over other constructional materials, for example, high strength-to-weight ratio, ease of fabrication, economy in transportation and the flexibility of sectional profiles, which make CFS ideal for modern residential and industrial buildings. They have been increasingly used as purlins as the intermediate members in a roof system, or load-bearing components in low- and mid-rise buildings. However, using CFS members in building structures has been facing challenges due to the lack of knowledge to th

Abstract A numerical framework for the prediction of acoustic damping characteristics is developed and applied to a quarter-wave resonator with non-uniform temperature. The results demonstrate a significant impact of the temperature profile on the damping characteristics and hence the necessity of accurate modeling of heat transfer in oscillating flow. Large Eddy Simulations are applied to demonstrate and quantify enhancement in heat transfer induced by pulsations. The study covers wall-normal heat transfer in pulsating flow as well as longitudinal convective effects in oscillating flow. A discussion of hydrodynamic and thermal boundary layers provides insight into the flow physics of oscillatory convective heat transfer.

An electrical field distorted by the complicated cable accessory structure and non-uniform temperature distribution is a significant threat to high voltage direct current (HVDC) cable. Thus, the field grading material (FGM) with nonlinear conductivity can uniform local field receives attention. This chapter focuses on the surface charge property of SiR/SiC composites effected by temperature. Field strength and SiC content have a positive effect on the increase in conductivity. When the temperature increases, the threshold field decreases. At high SiC content, this phenomenon is more obvious. The influence of temperature is considered under DC voltage and impulse superimposed DC voltage.

It is critical to maintain uniformity of gasket stress in control against leakage in piping and heat exchangers. Many innovative bolting tools have been developed, but their benefit could be downgraded if there were sources disrupting initially achieved uniformity of gasket stress, especially temperature differences in mating flanges and non-axisymmetric temperature. It is thus necessary to understand behaviors of flanges and gaskets with non-uniform temperature distribution. The impact of temperature differences in mating flanges with various types of gaskets on leak tightness was evaluated b

The problem is solved in the approximation of a thin concentration and temperature boundary layers in the droplet and in the surrounding air. We assumed that the bulk of a droplet, beyond the

The Molten Salt Reactor (MSR) is one of the six Generation IV systems capable of breeding and transmutation of actinides and long-lived fission products, which uses the liquid molten salt as the fuel solvent, coolant and heat generation simultaneously.

Therefore, it is very important to do some research on MSR, especially in accident conditions. The present paper studies the natural convection through which t

Calculations by employing non-uniform control volume for each subchannel have also been performed. This variation of control volume is due to the presence of wire spacer.
