CFD simulation of a free surface jet of high pressure nozzle. Jet sloping 90° 85° and 75°
Říha, Zdeněk
2017 - anglický
The report contains CFD results and description of the two phase flow water and air. Water comes into the computational domain through the nozzle which creates water jet. The jet falls on the wall surface where flows along the surface plate in all directions (x,y mainly). The aim of the work is to show how the falling water flows on the wall surface with help of advanced CFD model. Three cases had been solved there with a various jets sloping to the bottom surface plate. The first case contains results with configuration of the geometry for the jet sloping 90o. Second case contains results with configuration of the geometry for the jet sloping 85o and third case contains results with configuration of the geometry for the jet sloping 75o, see enclosures 1, 2 and 3. Given calculation had been done as steady state calculations.

Alternative Formulation of Pay-as-clear Auction in Electricity Markets
Aussel, D.; Červinka, Michal; Henrion, R.; Pištěk, Miroslav
2017 - anglický
In widely used formulation of pay-as-clear electricity market the clearing price is given by the Lagrange multiplier of the demand sat- isfaction constraint in the problem of the Independent System Operator (ISO). Following this idea, one may usually calculate the market clearing\nprice analytically even for problems of higher dimensions. However, the economic interpretation of such a market setting is in question, since the minimized criterion does not correspond neither to the cost of production nor to the overall payment of consumers. This observation motivated us\nto propose an alternative clearing mechanism where the total payment of consumers is explicitly minimized. We show existence and uniqueness of the clearing price in such a setting.
