We require a physicist or Hydraulic engineer to calculate the variables of a small scale closed circuit pumping system. The work will include calculation of forces produced by cavitation with fluid column separation hydraulic transients in closed (dead end) polymer pipes of small diameters. (3-12mm)
The aim will be to produce a mathematical model to predict the forces resulting from changes in system parameters within certain limits.
The pumping system consists of a polymer piston/ cylinder assembly driven by a linear actuator which can apply positive or negative pressure to the cylinder. The cylinder is connected to the closed end polymer tubing, in lengths between 2 and 7 metres in length.
The hydraulic medium is water or low-viscosity aqueous solution. The thermodynamics of the system will need to be considered in relation to the change in cavitation phenomena as a consequence of fluid heating with continuous work.
The deliverables would be:
(1) Mathematical proof.
(2) Conversion of proof to a predictive tool within Excel or Matlab to determine the consequences of changes in system variables, preferably with graphical output.
(3) Review of the model subsequent to lab testing of the system by us.
The work will be subject to completion of a Non-Disclosure agreement. System drawings and data will be subsequently provided for analysis in order to complete the work.
