AN EXAMPLE OF CRANIOPLASTY WITH THE ASSISTANCE OF 3D PRINTING TECHNOLOGY: A CASE REPORT
Cranioplasty is the surgical repair of a bone defect in the skull that is left behind after a severe injury or previous operation. It is usually done to protect underlying brain tissue, reduce local pain and to improve the cranial vault aesthetics. Cranial prostheses can be made from different types of materials: autologous bone, titanium, ceramics...

INFLUENCE OF CONTRACTION SHAPE ON THE FLOW QUALITY IN WIND TUNNEL TEST SECTION
Contraction is a part of a wind tunnel that has the greatest impact on the air flow quality in the test section. The constriction ratio, the cross section shape, the length and wall shape are constructive parameters that influence the uniformity of the flow, the flow turbulence intensity, the flow rotation angularity, the appearance of the flow sep...

NUMERICAL SIMULATION OF TWO-PHASE INTERFACIAL FLOWS
The paper presents the volume-of-fluid (VOF) method for interface capturing in free surface flows in OpenFOAM® software. The VOF-model utilises an algebraic compressive scheme to effectively shrink the transitional region between the liquid and the gaseous phase. The capabilities of the model are demonstrated by simulating two-dimensionalaxisym...
