This article will examine the early, systematic creation of exhaust system models at Volkswagen. The main subject is the validated modular and, consequently, easily modifiable design of a conceptual model of the system. Further, possible uses of the calculations of this model will be described....
If calculations indicate that an additional fraction of another filter is needed, a complete additional filter shall be added (SCDHEC, 2021). Filters are usually made removable by installing them in frames or holders constructed out of rigid and incombustible material. They are provided with ...
In instances where pulse energy recovery has been optimized, it is often possible, based on calculations using pressure and temperature losses across the turbine, to observe very high turbine efficiencies, which some experts say are in excess of 100%....
preferably more. This outflow should be included in the calculations of cell ventilation air flow. The scavenger flow is induced by a fan, preferably external to the building, usually centrifugal, which must be capable of handling the combined air and exhaust flow at temperatures that, if close...
engine and attempts to compare two types of exhaust systems whose advantages and disadvantages in analytical calculations are difficult to determine, whereas CFD tests accurately represent pressure fields, velocities and the most important parameter in the form of resistance of the exhaust system. The...
The coupled model turbine and model exhaust hood calculations and experiments were carried out to validate the effects of the optimization. Model experiments show that the design modifications resulted in a substantial increase in the overall pressure recovery coefficient. The flow and aerodynamic ...
Exhaust gas calculations Weight calculations Structural calculations Project specification Download specification Installation of a scrubber system is a major retrofit project involving several thousand working hours. To select a preferred system, which must be optimised in terms of size and placement, ...
Ideal solutions for design, manufacturing and erection of power plants and high quality products. Meet the finest exhaust systems
[97], the case-study calculations oversized the whole system by a factor of 2 or 3 times compared with the actual demand in a medium-load case, and by 1.4–1.8 times even with an extra-heavy load [99]. The type of appliances under the hoods is not considered in these methods. There...
