The ratio of the first condition flow rates p.sub.2 /p.sub.1 multiplied by the base orifice flow rate at condition two, p.sub.3, allows calculation of a theoretical flow rate for the first small orifice (or first head or piece of equipment) at condition two, p.sub.4. Once measured...
The effect of air-flow rates on the volatilization loss of NH3 from urea was studied on two soil types. In both soils, the volatilization loss increased wi... H Panchras,MK Yusop 被引量: 4发表: 0年 Air Flow Measurement by Image Analysis and Numerical Calculation of Flow Fields in a He...

A model for solids mass flow calculation in pneumatic conveying is presented. A horizontal pipe section is used together with pressure and air flow measurements for applying the model. The model has been validated successfully with experimental data from two conveying systems, four materials and in ...
To provide technique for obtaining the filling air quantity of an internal combustion engine with higher accuracy than before.;SOLUTION: Operation models 22, 24 of air filling quantity in a cylinder are adapted to find an estimated intake pressure Pe on the basis of an intake flow rate Ms, an...
The measurements are based on national norms, which are prescribed the measuring and calculation methodologies, type of measurement devices that are accepted, as well as the execution range for measurements. For large combustion plants requires continuous monitoring. The automatic devices that are used:...
By contrast, Models 3 and 4 provided complex meshes that complicate the convergence of the calculation and require a suitable treatment of both the viscosity and the flow near the walls. Model 3 showed the smallest error (16%) in the air velocity estimated in the treatment plane. Model 4 ...
To simulate indoor airflow more quickly while getting satisfied results for engineering projects, a new approach called N\|point momentum model is proposed to describe boundary conditions of air terminal devices in computational fluid dynamics (CFD) calculation. The new air supply opening model (ASOM...
The calculation of airflows is of great importance for detailed building thermal simulation computer codes, these airflows most frequently constituting an important thermal coupling between the building and the outside on one hand, and the different thermal zones on the other. The driving effects of...
