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...

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...

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...

The paper analyzes the behavior of the plastic container during the buckling, ie during the load effect on the containers. The analysis was experimentally performed on several different types of containers. The container material is polypropylene. Experimental determination of pressure force and corresponding deformation was performed in thelaborat...
