Key Projects undertaken in InfoTech for Pratt and Whitney, USA: 1. Analyses of flow characteristics in axial- gap and overlap seals for turbine stages: A number of unsteady analyses were done with axial-gap and single/double overlap seals to investigate hot air ingestion in the rim cavity in turbine stages. Standard k- and k- SST turbulence models were used with standard wall function. k- SST showed better agreement of results with data. 2. Extraction of Heat Transfer coefficient from CFD results: The purpose of analyses carried out under this program is first to see if the direct heat-transfer coefficient extraction yields reasonable result and secondly to improve the existing correlations using the CFD results. 3. Analysis Of Flow Inside a Rotating Cavity: 2D axsymmetric analyses were carried out on a rotating cavity that supplies cooling air to the Turbine Blades. The inlet to the rotating cavity receives air that has a significant amount of swirl in it. A user-defined function was written for fixing constant specified swirl velocity at the inlet. Standard k- turbulence model was used with enhanced wall treatment for better resolution of boundary layers. This analysis was carried out to investigate the root cause of a high temperature zone observed in HPT disc. 4. Analysis Of Flow Inside High Pressure Compressor Rotor Cavity: The analysis was done on Drum Rotor Cavity of the High Pressure Compressor in a 2D domain. A constant swirl velocity at the cavity inlet is specified and momentum source terms for modeling the drag effect of the bolts are incorporated by a user-defined function. The distribution of RPM factor at various locations in the domain was given to the thermal analysis team. 5. Analysis Of Flow Inside Fan and Low Pressure Compressor Rotor Cavity: 2D axisymmetric analysis was carried out on Spinner and Drum Cavity of the Fan and Low Pressure Compressor. User Defined Function was written for fixing constant specified swirl velocity at the inlet and, momentum source terms for modeling the effect of drag of bolts. The output of this analysis was the RPM factor distribution for carrying out thermal analysis of the cavity.
Project Asistant sep. 2007 To Aug. 2008
Key Projects undertaken in BHEL (R&D), Hyderabad: Project #1: Title : Live Project on “Cooling Water Sump Model for Power Plant”. Client : GIPCL, Gujarat. Place of work : Center for Excellence CFD Dept., BHEL (R&D), Hyd. Team size : 2 members. Role : Modeling, Meshing & CFD Analysis. Software’s used : Auto CAD, I-deas/Catia V5, ICEM-CFD & CFX-11. Description : A scaled down models for C.W sump was analyzed for overall flow pattern, swirl angles around the various locations of the three pump intakes. The sump geometry consisted of inlet channels, fore way, stop log gates, pump chambers and suction pipes with and without spurs & vortex breakers. The geometry modeling of C.W sump is carried out using IDEAS/CATIA-V5 and mesh generation is carried out using ICEM-CFD. During mesh generation I have used different types of meshes like Hexa, Tetra & Prism layers for obtaining improved quality of cells. After the proper mesh generation, a two phase free surface model was used to define the volume fraction of air and water. Converged solutions were obtained for max. And min. water levels through CFX-11. The swirl angle was computed below the pump intakes. The geometry with spurs & vortex breakers improved flow path and reduced swirl angles. Project #2: Title : Live project on “Flow Analysis on secondary steam of existing and Upgraded Advanced Steam Generator”. Client : BHEL, Trichy. Place of work : Center for Excellence CFD Dept., BHEL (R&D), Hyd. Team size : 4 members. Role : Modeling, Meshing & CFD Analysis. Software’s used : Auto CAD, I-deas/Catia V5, ICEM-CFD & Fluent6.3. Description : Upper portion of the nuclear steam generator was modeled for investigating various flow parameters. The two configurations was modeled, one with single hole venturi and other with 7 hole venturi’s. I have modeled the upper portion of advanced generator for 500MW & 700MW nuclear power plants. The geometry consisted of outer dome, drier box, perforation plate and nozzles. The geometrical modeling was done in I-deas/Catia-V5 and mesh generation was done in ICEM-CFD. In ICEM different mesh topology was used for various components, hex mesh was generated for outer dome, drier box, nozzle and tetra mesh for perforated area. Suitable interfaces were generated and boundary conditions set-up made for obtaining converged solutions in Fluent. The main objective of the project was to study the flow path behavior, computation of pressure & velocity profiles at different sections of geometry and estimation of total pressure drop & choking mass flow. Project #3: Title : Live project on “0.7 sq meter Low Pressure Turbine Module of Actual & Modified Configurations”. Client : BHEL, R.C. Puram, Andhra Pradesh. Place of work : Center for Excellence CFD Dept., BHEL (R&D), Hyd. Team size : 2 members. Role : Modeling, Grid Generation & CFD Analysis. Software’s used : Auto CAD, I-deas, TurboGrid-11, CFX-11. Description : The main objective of this project is to carry out the CFD Analysis of 0.7 sq meter Steam Turbine LP module of Actual and Modified case. The analysis is carried out for the complete module including inlet, blade path of the turbine. The flow domain for all the stages is modeled together with necessary mesh interfaces between the stages. Analysis was carried out for design and off design conditions. Flow field variables like pressure, velocity were obtained which helped in visualizing the flow of fluid in the domain. The results of the current CFD Analysis are compared with the available two dimensional analysis results. In the next step Modified Turbine case, Moving and guide blade arrangement was changed to increase the flow passage and allow more mass flow. This arrangement was tested for varying rpm of the turbine. Results were analyzed for overall performance of the Modified turbine. Final Year B.Tech Project : Title : Live Project on “CAD Modeling & CFD analysis of ID Fan”. Place of work : Center for Excellence CFD Dept., BHEL (R&D), Hyd. Team size : 2 members. Client : BHEL, Ranipet. Duration : 4 months. Role : Modeling, meshing & analysis. Software’s used : Auto CAD, I-deas, Turbo Grid & CFX-5.7. Description : Typical power station has a number of turbo machinery equipment such as steam turbines, boiler, feed pump, PA fans; ID (induced draught) fans etc.our project deals with CFD analysis of ID fan for a typical power station.ID fan are axial blowers meant to create the suction pressure upstream and deliver the flue gases to chimney. These fans have flows with small ash contents. The flow passes through inlet suction chamber, inlet guide vanes, axial impeller, outlet guide vanes and diffuser. Some times improper distribution of flow causes erosion due to ash. CFD analysis by proper geometric and computational modeling (mesh generation) of all these components will reveal the flow paths inside the machine. The performance is also predicted through CFD analysis. The modeling of Induced Draft fan assembly is carried out using IDEAS software. The meshing is carried out using ICEM-CFD, TURBOGRID based on convergence criteria. The various boundary conditions are imposed and solution is carried out using CFX solver. Velocity profile, pressure drops, efficiency and power are estimated from the post processing.
