The comparison of needle penetration and cone penetration test of asfalt rubbers
Sychra, Martin ; Dašek, Ondřej (referee) ; Kudrna, Jan (advisor)
The laboratory properties of crumb rubber modified bitumens (dynamic viscosity, needle penetration, cone penetration, softening point, resilience and elastic recovery) are determined in bachelor’s thesis. The relationship between these properties is described.
Study of the Gas Blow-by through the Turbocharger Sealing System
Požár, Vladimír ; Novotný, Pavel (referee) ; Vacula, Jiří (advisor)
The work focuses on the investigation of gas flow within the sealing system of a turbocharger, specifically in the compressor section. The sealing „piston” ring located here is the main subject of the study, primarily examining the influence of the ring's geometry and its positioning in the shaft groove on gas leakage into the bearing housing. Furthermore, the behavior of this flow under various boundary conditions is assessed by testing different flow types.
