Heat exchangers are one of the most used and important devices in modern industry, as well as in residential sector. There is no ideal heat exchanger. As a result, there are many types of heat end mass exchangers. The design differs according to the capacity, temperature, pressure, type of work fluids and other factors. As several different types o...

The toroidal cutting edge, also called corner cutter, is a combination of the cylindrical-frontal milling cutter and the spherical head milling. The paper follows at generating the optimal trajectory for making the finished product with the toroidal cutting edge without having to use the flat end mill and the ball nose end mill. This trajectory is ...

This work presents computer simulation of mold filling and crystallization for a two-blade drill bit steel billet. Drawing-based models of a two-blade drill bit and its detachable casting mold were developed by SolidWorks. The developed solid model was transferred to the ProCAST program. The preliminary stages of a drill bit cast molding computer s...

Electronic properties of pulsed laser deposited, nanoscale CeNi5 alloy layers, on a dielectric substrate are described using the complex dielectric function. This spectral behaviour is studied separately for the real part ε1 (the dielectric constant or dielectric permittivity) and imaginary part ε2 (the dielectric loss function) of ...
