Investigation of the Effect of Using 3D Airfoils in the First Row Blades of v94.2 Gas Turbine Compressor Using CFX Software
, M.Sc. Thesis Sharif University of Technology ; Ghorbanian, Kaveh (Supervisor)
Abstract
CDA and NACA65 airfoils, originally designed for aircraft engine applications so do not have the best possible performance for heavy-duty industrial gas turbines and should be optimized according to the operating conditions and requirements of these turbines. For example, due to the high mass flow in industrial gas turbines, the first rows of the compressor deal with the distribution of critical velocities and sound level, while in the middle and end rows of the flow, the flow is subsonic. In designing these airfoils, two parameters of wide performance drop and range should be considered. Since the diffusion of the suction surface causes a drop, the design of new airfoils should start with...

Abstract
Cell-laden hydrogel microcapsules enable the high-throughput production of cell aggregates, which are relevant for three-dimensional tissue engineering and drug screening applications. However, current microcapsule production strategies are limited by their throughput, multistep protocols, and limited amount of compatible biomaterials. We here present a single-step process for the controlled microfluidic production of single-core microcapsules using enzymatic outside-in cross-linking of tyramine-conjugated polymers. It was hypothesized that a physically, instead of the conventionally explored biochemically, controlled enzymatic cross-linking process would improve the reproducibility,...
