Simultaneously, monthly sampling of gas exchange was conducted using non-steady state chambers in four distinct land-cover types in the wetland: open water, emergent vegetation (Typha spp ., floating vegetation (Nelumbo spp).
Forest-floor CO2 efflux (Rs) measurements were made continuously with an automated non-steady-state chamber system as well as at 2 4 weekly intervals with manual non-steady-state chambers.
The steady-state chamber value of Ceq = 0.7 ppm measured for chipboard by Andersen et al. (230) at T = 22 °C and r.h.
On the basis of these findings, Andersen et al. have formulated a relationship (eq 19) between the steady-state chamber concentration Css and the climatic parameters.
Non-Flow-Through Steady-State Chambers for Measuring Soil Respiration: Numerical Evaluation of Their Performance.
The static chamber method (non-flow-through-non-steady-state chambers) is the most common method to measure fluxes of methane (CH4) from soils.
Gas exchange measurements were carried out in early June, between 8.00 am and 12.00 am, with a steady state through flow chamber (PLC4, PP-Systems, Hitchin, UK) coupled with an infra-red gas analyzer (CIRAS II, PP-Systems, Hitchin, UK).
Vacuum chambers of Steady State Superconducting (SST-1) Tokamak comprises of the vacuum vessel and the cryostat.
Physical models take into account mass and thermal balances at the steady state inside of the evaporation chambers and condensers through a Number of Transfer Unit – Efficiency model.
The ignition process was less affected by the spraying condition (Wea), except that the change of the spraying condition influenced ignition to steady state transition, such as a combustion chamber pressure overshoot.
A steady state CFD simulation of the combustion chamber and glass tank shows that a side-fired burner configuration allows for lower gas velocities and temperatures close to the glass and the furnace walls while guaranteeing the same heat transfer characteristics to the glass than the more traditional end-fired (U-type) furnaces.
