About

Background

Dr Sham Rane graduated in Mechanical Engineering from the University of Pune. He then worked as a manufacturing engineer at Forbes Marshall India Pvt. Ltd. where he worked on boiler fabrication, oil fired burner prototyping and testing, steam engineering and process plant engineering. He continued his education at Indian Institute of Technology Delhi in the Mechanical Engineering department with specialization in Design of Mechanical Equipment.

In 2008, Dr Rane joined the computational fluid dynamics department of ANSYS FLUENT India Ltd. and worked as an application engineer for FLUENT and CFX codes. At ANSYS, he has worked on customized UDF development, Multiphysics code coupling between Fluids and Electromagnetic solvers and development of grids.

In 2011, he moved to London and joined City University’s Centre for Compressor Technology for his PhD research. Here he works extensively on deforming grid generation for twin screw compressors. He investigates non-classical rotor designs like variable lead and variable profile using CFD analysis.

In 2014, Dr Rane completed his thesis and was appointed as a Research Fellow at the centre to carry further developments in CFD analysis in positive displacement machines. Recently he has been working on analysis of multiphase flows in twin screw compressors such as water spray and oil injected designs. He has also been working on extension of the CFD modelling to oil injected and ORC application rotary vane compressors and expanders.

Dr Rane has been involved in development and commercialization of the grid generation technology at the centre and works actively in software development which is available as SCORG tool via PDM Analysis Ltd., UK for industrial and academic research.

Variable Lead Rotors

His recent work on improving deforming meshes has been applied for oil injected twin screw compressor analysis in the industry and research. A fellow researcher at the centre has used the same grid technology for twin screw pump analysis and investigation of cavitation in these machines. The research work has attracted attention from other positive displacement machine developers and a recent extension of the model was done in the ORC application of vane expanders and compressors.

EPM767 - Screw Compressor Design

MATHEMATICAL MODELLING IN COMPUTER AIDED
DESIGN OF SCREW COMPRESSORS
Recent advances in computer modelling of compressor working processes have made it possible to predict compressor performance far more accurately than by traditional methods based on simplified calculations. Moreover, the speed at which such calculations can then be performed permits the effect of variation of the principal design parameters on performance to be reliably estimated. It is thereby possible to produce fully optimized designs for any specific duty with the minimum amount of change during the development programme. By use of a CAD system, results of such calculations can be transferred directly to the production of working drawings. The course covers only the basics of Positive Displacement Compressors and some more details of the two main types of these compressors currently in use in the air compression and refrigeration industries, namely the screw and scroll.
The core course syllabus consists of full details screw compressor models including descriptions of geometric models of screw compressors, models of the thermo-fluids processes of admission, compression and discharge, including leakage and fluid injection, pressure load calculations, performance analysis and parametric studies.
The course consists of lectures, discussion and laboratory classes, handouts and model software and participants will be given the opportunity to carry out hands on design studies under the direction of the course tutors, using the software supplied.

  1. 10th International Conference on Compressors and their Systems 2017. City University London (2017).
    Description: As a result of the success of the 9th London International Compressor Conference the 10th in this series will be extended to cover three full days. As in the 9th conference, the programme will include a full session dedicated to industrial issues of a non-technical nature, in addition to the traditional keynote addresses, research and technical papers, podium papers and discussions.

    Featuring participation by manufacturers of compressors, expanders and systems and control systems, equipment suppliers, users and research organisations. This conference provides a forum where developments in air, gas and refrigeration compressors, vacuum pumps, expanders, related systems and components
    can be presented for discussion.

  2. Short Course on Computational Fluid Dynamics in Rotary Positive Displacement Machines. City University London (2017).
    Description: 3rd CFD Short Course

    Following the success of two previous forums/short-courses, on CFD in Positive Displacement Machines (PDM), in which there was strong participation from the compressor industry, CFD software providers and academia, the third event is dedicated to advanced topics in the application of CFD to PDM for industrial use and research. Topics to be covered include: grid generation, advances in CFD methods, multiphase and turbulence modelling, validation of CFD predictions, CAD integration and Industrial applications.

    It was concluded from the results of the first two forums, that to increase the understanding of flow in compressors the following aspects of CFD in compressors need to be investigated further:
    1) Accurate prediction and sensitivity of clearance size variation during operation on the leakage flow through the machines.
    2) How modern CFD tools could be used to predict variation in gap size.
    3) Stability and accuracy of Multiphase flow calculations in 3D simulations of compressors.

    Participants from industry and academia are encouraged to present their research and analysis to the forum during the short-course. As with the 2nd short-course, laboratory, a dry air screw compressor test results are available to aid the above investigations. Talks covering theoretical aspects, as well as practical applications, will be presented at the short-course and attendees will benefit by getting an insight into the current state of the art.

    The Forum/Short Course will be held at the Northampton Square site of City University of London prior to the 10th Conference on Compressors and their Systems on Saturday 9th and Sunday 10th September 2017.
