Below for adopting described experimental provision to carry out the theoretical foundation of saline experiment.The basic theories of salt water model test can be summarized with the analogy of heat and quality transmission, and in building fire, the motion of the buoyancy of flue gas is simulated with the density difference in clear water.Brine density is greater than clear water density, and flue-gas temperature is higher than ambient air temperature, as long as both governing equations are consistent, two kinds of motions just may realize similar.In building fire process, spatial altitude is H, and burning things which may cause a fire disaster heat dissipation capacity is Q, and buoyance flux is B, and its characteristic quantity is defined as follows: characteristic length is height space H and h, and characteristic velocity is U=(B/H)
1/3and V=(b/h)
1/3, the characteristic time is τ=H/U and τ=h/V, through zero dimensionization, processes, the governing equation of flow of flue gas is:
The poor Fluid Control Equation causing of brine density is:
K wherein
i=(0,1,0),
,
, each criterion numeral is respectively:
Flow of flue gas:
,
,
Saline flow:
,
,
As can be seen here, smoke movement is identical with the governing equation form of saline flow, if both criterion numeral Re, Fr, Pr, Sc equate respectively, the two is similar.
Two on all four necessary and sufficient condition of phenomenon are: (1) geometric similarity; (2) inlet flow situation is similar; (3) physical parameter of each corresponding point is similar; (4) boundary condition is similar; (5) criterion numeral of the same name equates.Wherein criterion equates it is to be difficult to most realize comparatively speaking.Re number is to determine the mechanically similar major parameter in flow field, and the general mobile Re order of magnitude of smoke plume is 10
5, the Re order of magnitude of salt water sport is 10
4, the two is unequal, but the two has all reached turbulent flow state, now can think that the impact of Reynolds number flow is not bery important.Fr number represents the ratio of inertial flow power and gravity, and Fr number when actual checking computations show flue gas and saline flow is the same order of magnitude.Pr number and Sc number represent physical properties of fluids criterion numeral, and the former determines the mobile length of flue gas and the similarity degree of velocity field, and the latter determines the similarity degree of brine concentration field and velocity field.In the scope of discussing at present, these two dimensionless numbers are respectively turbulent flow Pr
tnumber and turbulent flow Sc
tnumber, the two is all close to 1, can think their approximately equal.In sum, it is feasible by saline flow, coming simulated flue gas to flow.
Just utilize the calculating of certain skyscraper heating and ventilating equipment air-supply fume-resisting system to describe below.Adopt multizone network analog software CONTAM, be the subordinate of USA National Institute of Standard and Technology (NIST) the exploitation of building fire research laboratory for multizone Air Flow and dispersion of pollutants.The building smoke control system that CONTAM software can be combined use to pressure air blowing between architectural stair, regional area smoke evacuation or the two is researched and analysed.
Totally 39 layers of certain skyscrapers, every aspect is amassed about 2000m
2, floor height 3.5m.Be assumed to be winter, outdoor temperature-15 ℃, pressure 101325Pa, ignores the impact of outdoor wind speed, supposes that indoor temperature is 22 ℃.The area of each circulation path is as follows: elevator door size 2.0m * 2.0m, gap area 0.06m
2, the doors of stairwell size 2.0m * 1.6m, gap area 0.0184m
2, window size 1.6m * 1.2m, gap area 0.0361m
2, elevator top smoke vent area 10m
2.Fire bed at two layers, the room temperature of supposing to catch fire is 700 ℃, and during breaking out of fire, each door and window is in closed condition, and stairwell, elevator well temperature are assumed to be 50 ℃.Institute's emulation mode is stable state, and result temporal evolution not, is below the analysis of each condition calculating;
(1) without pressure air blowing
As calculated, it is 9.8kg/s that stairwell calculates ventilation, and it is 74.2kg/s that elevator calculates ventilation, and stairwell, elevator " neutral plane " position are respectively 24 layers, 35 layers of buildings.Therefore, the above air of 24 layers of stairwells outwards flow, and 24 layers of following air enter, the flue gas that produces of fire bed enter stairwell, can cause the expansion of building fire; 35 layers of following air of elevator flow into, and 35 layers of above air outwards flow, and flue gas can enter each floor area, causes building fire to expand and reduce the security of floor area.
(2) only stairwell pressurization air-supply
Only, to stairwell pressurization air-supply, pressure air blowing amount is 40000m
3the high rule of/h(< < > > regulation 36000 ~ 40000m
3/ h), every layer of about 1000m
3/ h.As calculated, in elevator, " neutral plane " position, at 35 layers, remains unchanged substantially with institute's calculating location in (1) operating mode; Stairwell interior " neutral plane " is below building bottom, and stairwell air flows out by gaps such as door and windows.The doors of stairwell both sides pressure reduction is increased to 150Pa along building height by 35Pa, be the pressure reduction that stair door both sides, upper floor region pressure reduction has surpassed the high rule of < < > > regulation 50Pa, now stair door is opened difficulty, is unfavorable for personnel escape.
(3) floor area pressure air blowing only
Facing to the above floor area of fire bed, utilize hvac equipment air output, every layer of air output is 7000m
3/ h(, in order to meet the calculating air output of human thermal comfort, can estimate according to rate of ventilation).As calculated, more than elevator " neutral plane " is promoted to building general height, in whole solitary building, air or flue gas flow into elevator, by elevator top exhaust opening, drain into atmosphere, and exhaust smoke level is 84.8kg/s; Stairwell interior " neutral plane " maintains 24 layers, and calculating ventilation is 12.5kg/s.Changing every layer of air output is 9000m
3/ h, result of calculation shows that " neutral plane " is still more than building general height, exhaust smoke level is 92.5kg/s; Change elevator top smoke vent area, bring up to 15m
2, result of calculation shows that " neutral plane " is still more than building general height, exhaust smoke level is 102.8kg/s.
In sum, building is discharged fume by elevator top exhaust opening after breaking out of fire, utilizes the hvac equipment pressurization of blowing, more than can realizing elevator " neutral plane " being highly increased to building general height, thereby stop flue gas to invade floor area, avoid fire further to expand.Hvac equipment air output adopts human thermal comfort to calculate air output and can meet the demands, and elevator top smoke vent area is larger with exhaust smoke level impact on " neutral plane ".
Test unit of the present invention can intuitively show the impact of above-mentioned hvac equipment air-supply on flow of flue gas in elevator.
