CODE 65894 ACADEMIC YEAR 2016/2017 CREDITS 6 cfu anno 2 INGEGNERIA MECCANICA - ENERGIA E AERONAUTICA 9270 (LM-33) - SCIENTIFIC DISCIPLINARY SECTOR ING-IND/08 LANGUAGE Italiano TEACHING LOCATION SEMESTER 1° Semester AIMS AND CONTENT LEARNING OUTCOMES The course aimes to provide a critical knowledge of the design procedures employed in the design of turbomachines. The performance required by the energy system in which the machine is used is considered, together with the characteristics and the matching with the other components of the system. TEACHING METHODS Theoretical lectures and computational exercises. SYLLABUS/CONTENT Application of Continuity, Energy, Momentum and Euler equations to turbomachines. The preliminary design, based on similarity and statistics. Axial machines: mean line design. Radial equilibrium equation. Different vortex laws (free vortex, forced vortex, exponential and fixed angle). Effects of enthalpy variation and entrophy radial gradient effects into the flow angle distribution. Correlations. Centrifugal turbomachines: the blade loading and the blade shape; employ in the design problem. Slip factor effects and correlations (Stanitz, Stodola, Busemann, Wiesner). Japickse’s criterion for the loss evaluation inside centrifugal impeller. The jet and wake model. Logarithmic spiral trajectory. The design of the vaned and unvaned diffusers. Design of the volute.
