Thermoelectric generators (TEGs) which convert heat into electrical energy due to Seebeck effect, have recently attracted a great attention as green and sustainable energy sources. One of the challenges in the field of thermoelectric devices is the design optimization in order to make ... Read More

Deformation prediction is an important part of the structure stability analysis. However, the deformation of bank protection structure which is affected by many factors, such as structural stiffness, earth pressure and hydrostatic pressure. It contains a complex mechanical process, which ... Read More

With the extensive application of ground freezing method in coastal areas, the groundwater environment during ground freezing has been changed. Especially in seawater intrusion areas, groundwater salinity is high (even salinity equivalent to sea water (ca. 35g/L)). Engineering experience ... Read More

We consider the fluid dynamics problem of homogeneously filling a large tank by multiple inlets fed from a piping system. Suitable pipe geometries must be chosen so that the volume flow is constant for all inlets. In this work, we compare both for a piping system as depicted in fig. 1: A ... Read More

Machines with rotating components are prone to vibrations because an imbalance of the rotor would always act as a harmonic excitation force to the machine. Thus oscillations close to the natural frequencies are tried to pass through fast in the run-up and cast-down or even completely ... Read More

Graphene is an allotrope of carbon having the structure of a plane sp2-hybridized atom with a band length of 1.42Å, and representing the basis of any carbonaceous material. This 2D material consisting on pure forms of carbon exhibits high crystalline and electronic quality. Thus, despite ... Read More

Numerical simulation tools offer the opportunity to ascertain characteristic values, which are difficult to measure. A possible approach for validating simulation models by easy measurable data and gaining the needed values is described in this study of a Venturi tube. The examination of ... Read More

Dedicated work in modeling, simulation and design optimization of Lithium-ion Battery (LIBs) was done in the past decades, and still, the most widely used one for electrochemical processes is the Newman model. [1] The underlying parameters are treated deterministically, but the impact of ... Read More

Stirred tank bioreactors are used to simulate a natural biochemical environment for the optimum growth of cells (i.e. algae, microorganisms or tissues) in microbial and cell culture. Bioreactor types range from small (5 L and less) up to 15000 L systems for large-scale industrial ... Read More

This paper presents a measurement type 4000/5A current transformer which has 4 primary bars. The magnetic circuit of the prototype can be separable presenting easy installation inside the distribution panel. Time domain and frequency based simulations are obtained and the electric ... Read More
