Thermal systems in small devices like cooling electronic chips require efficient technologies with diameter channels. These have laminar flow and disrupted boundary layers, leading to high pressure drop values. To ensure sufficient limit coolant temperature, a possible solution is dynamically deform one channel wall mimic pumping disrupt creating peristaltic effect, called dynamic heat exchange...

Object-oriented heat-exchanger models were developed to simulate the dynamic thermal effects of dynamic changes in fluid composition and thus of fluid properties in a type of liquid typical for food products. The models were written in the object-oriented language Modelica as objects in a library structure being developed to simulate complex liquid food process lines and their control systems. ...

Computational Fluid Dynamics (CFD) deals with computing the equations of fluid flows using numerical methods instead of partial differential equations. The Discrete-Event System specification (DEVS) theory has already been used to approximate various continuous systems by applying a quantized state system approach. In this research, we experiment with a new method: using Cell-DEVS theory to cre...

In this research experiment computational fluid dynamic (CFD) models were constructed, within Ansys Fluent TM v.R1, to investigate phenomena occurring during the Vertically Upwards Continuous Casting (VUCC) of 8 mm diameter, oxygen free copper (OFCu) for alterations casting speed. The simulated influence heat transported over a 0.1 air gap formed die was investigated and value wall transfer coe...
