We start in Section 2 with the definition of the discrete (standard) cylinder as an example of a discrete CMC-surface in the sense of Bobenko and Pinkall [3, 4] (Definition 2.4). This will also lead to the introduction of so called extended frames for discrete CMC-surfaces. These definitions will describe the discrete analogues of CMC-surfaces without umbilics in an isothermic parametrization. ...

The flow interception efficiency, which provides a measure of the fraction of streamlines that intercept a porous collector, is an important parameter in applications such as particle capture, filtration, and sedimentation. In this work, flow permeation through a porous circular cylinder located symmetrically between two impermeable parallel plates is investigated numerically under different fl...

sometimes the need for non-circular ducts arises in many heat transfer applications because of lower pressure drop of non-circular cross section such as square duct compared to circular tube, particularly in compact heat. but square cross section has poor heat transfer performance and it is expected that using a nanofluid as a new heat transfer media may improve the heat transfer performance of...

The intensity of high-order rainbows for normally incident light and certain rotation angles of a cylinder with an elliptical cross section is greatly amplified with respect to the intensity for a circular cross-sectional cylinder. The amplification is due to a number of the internal reflections occurring past the critical angle for total internal reflection, and the effect is especially strong...

Two new integrated models with heat source–heat sink are established, in which isothermal liquid cooling channels triangle or square sections are, respectively, embedded a cylindrical heating body uniform production. Based on constructal theory, under the conditions of fixed cylinder cross-sectional area and proportion channels, taking dimensionless maximum temperature entransy equivalent therm...

When electric potential is applied to conductors an electric field is created, which in turn creates arbitrary potentials between conductors. This is a study of the potential, electric field and charge involved in conductors. This also discusses capacitance of arbitrary conductors and how that is related to charge. Specifically this will discuss a concentric square cylinder capacitor like that ...
