The purpose of this work is to design and determine the performance of a prototype centrifugal pump impeller for an organic Rankine cycle (ORC) power plant of maximum power 100 kW. The centrifugal pump is especially designed to work on the same shaft as the corresponding ORC microturbine. The ORC unit works on R7100 (HFE7100) – a lowboiling fluid characterized by a zero ozone depletion potential coefficient. The pump has the following rated parameters: nominal flow rate of working fluid 4 kg/s, operating rotor speed 10 000 rpm. The pump designed by means of the 0D meanline method is subject to computational fluid dynamics (CFD) calculations and analysis. The obtained flow field results are discussed and performance characteristics of the pump are presented. The non-cavitating operational region is determined for the pump.

The recast of the European Insolvency Regulation, which has been applicable from 26 June 2017, implements a philosophy of Euro universalism, according to which in solvency proceedings opened in a Member State where the debtor has its centre of main in terests (COMI) should have a universal scope and encompass all the debtor’s assets situated throughout the EU.

The wording of the Recast Regulation is in tended to comply with the ECJ case law concerning COMI, such as Interedil, Eurofood, Bank Handlowy or Mediasucre judgments. Nevertheless, it is now questioned whether the Recast Regulation strengthens or rather weakens the COMI/registered office rebuttable presumption and opens the gate for in solvency forum shopping.

As far as international company law is concerned, the issue of transfer of seat as well as forum shopping has been widely discussed. So far the ECJ has issued a series of judgments in which it has explained the European freedom of establishment and the cross-border activities of companies in the internal market.

Similarly, the US Supreme Court has issued several significant decisions, such as CTP Corp. v. Dynamics Corp. of America, Edgar v. MITE Corp., and International Shoe Co. v. State of Washington, in which the limits of acceptable forum shopping are better delin eated.

Based on the aforementioned, it may be concluded that European harmonization measures facilitating cross-border mobility should additionally assist in achieving predictability and efficiency, as well as the economic viability and security of the operations under consideration.

This contribution analyses and expounds on the lessons that can be learned from both the ECJ case law as well as US Supreme Court’s decisions on in ternational company law, in cluding an examin ation of their effect on in solvency forum shoppin g. There is no doubt that, if successful, harmonized legislation on these matters would be a great asset for the internal market.
