History<\/span><\/strong><\/span>\n

The Laboratory of Fluid Mechanics & Turbomachines (LFMT) is one of the first laboratories of the University of Thessaly, founded in 1995 by Presidential Decree PD50\/95<\/a>. The Laboratory is equipped with scientific equipment suitable for teaching, research and service provision.
<\/span><\/p>\n

Objective & Activities<\/span><\/strong><\/span><\/p>\n

The focus of LFMT is on phenomena and effects of flow of fluids and polymers by using experimental measurements and computational modeling. The specific fields acting the <\/span>LFMT lab are gas-thermodynamics, combustion, atmospheric pollution, natural flows and all process including flow and transport phenomena in one-phase or multiphase flows.<\/span><\/p>\n

\u201cCharacterization of Contrast Agents for Medical Imaging and Drug Delivery with Ultrasound via Theoretical & Numerical Analysis of Static & Dynamic Response\u201d. Research project funded by the Greek Ministry of Education, carried out by the group led by Dr. Pelekasis as Coordinator. The total funding was 325000\u00a0\u20ac and covered the salaries of 2 PhD candidates and 3 Post Docs. Details on the activities of the project are provided in the wiki <\/span><\/span>http:\/\/contrast-aristeia.mie.uth.gr\/wiki\/<\/a>.<\/span><\/span><\/p>

The ARISTEIA I project provided convincing evidence regarding the mechanical behaviour of coated microbubbles as well as ways to obtain reliable estimates of their viscoelastic properties via static and acoustic measurements and the corresponding static and dynamic response patterns. The NIARXOS and Young Researcher Projects are essentially continuations of the ARISTEIA project, aiming at establishing the basis for successful implementation of such bioparticles in novel biomedical modalities.
