CASE STUDY

CFD: COMPUTATIONAL FLUID DYNAMICS  How does it help?

PUE calculus (Power Usage Effectiveness)

Air conditioning performance and energy output optimization of the coach

Modeling of extraordinary situations (disconnect air treatment units, etc.)

CFD is recommended in these cases.

Modeling of lay-out modifications

It is possible to adapt to no conventional patterns

CFD is used in clean rooms and other HVAC (Heating, Ventilation and Air Conditioning) special applications

CASE STUDY Initial design

Modified design

Objective accomplished?? Yes Final design

No CFD analysis with other design options

In the present case study we can distinguish the following steps: 1) Initial design analysis. 2) Identifying the present problems with a CFD analysis. 3) Proposals to solve the existing problems. 4) CFD analysis to verify if the proposals satisfy an optimal design.

HVAC IN TRAIN COACHES • Mesh:

HVAC IN TRAIN COACHES • Temperature: It is possible to do a detailed zoned analysis. In the small picture, it is observed the temperature distribution close to the legs of the passengers.

HVAC IN TRAIN COACHES • Temperature: Temperature distribution the volume.

in

HVAC IN TRAIN COACHES • Velocity: The velocity around the seats, let us know the location of stagnation areas and the location of places with problems to be ventilated. It also give us the information of the comfort level for the passengers.

HVAC IN TRAIN COACHES • Velocity: The streamlines shows, that the flow distribution is uniform.

HVAC IN TRAIN COACHES • Velocity:

Velocity distribution in the volume.

CONCLUSIONS FROM CASE STUDY •

HVAC objectives: – It has to be warranted the air renewal inside the coaches. – The temperature must not be too high or too low, for the comfort of the passengers. – Energy costs and efficiency of the ventilation system optimization.



Ventilation design: – Location and measures of the supply and exhaust grills.

CONCLUSIONS The use of CFD provides us: – A detailed analysis of the ventilation systems, before even constructed. – A view of the consequences of any modification in the ventilation systems in a fast way. – To find high risk locations and locations with worse ventilation. – Design optimization takind into account the PUE improvement. – Extraorinary scenarios modelization, and anticipate the needed measures to minimize their impact. – Complex geometries modelizations, that other softwares can not analyze. – Big economic losses prevention, because of not making a correct design of the ventilation systems.
