London is the capital and largest city of England and the United Kingdom.[7][8] Standing on the River Thames in the south-east of England, at the head of its 50-mile (80 km) estuary leading to the North Sea, London has been a major settlement for two millennia. Londinium was founded by the Romans.[9] The City of London, London''s

### TIME SCALES IN UNSTEADY LIQUID-FILLED PIPE FLOWS

The Netherlands United Kingdom ABSTRACT Time scales are used to classify unsteady flow in liquid-filled pipes. Seven types of pipe flow are distinguished, with time scales ranging from infinity to zero. Nothing happens when the time scale tends to infinity

### Periodic boundary conditions

22/5/2012· Actually yes this exactly means that the problem is now 1D. I have seen the manual describing the use of periodic boundary conditions in 3.5(a) but they have used a Dirichilet boundary condition on temperature at the inlet while a convective flux at the exit the b.c
