fire especially wildfire is really
complex phenomena I hear people talking
about being able to control fire I don’t
think that’s something that will happen
soon but here we are at least trying to
understand fire
there’s factors that affect fire from
the individual leave clear up to the top
of the atmosphere the current model that
we use to print help us predict fire
spread it was about 40 years old and so
what we’re doing with these experiments
is probing deeper and trying to provide
more information about how fire spreads
in wild lands today we’re gonna run
different types of experiments and we’re
trying to understand under which
conditions the fire if it ignites in the
surface will transition and spread so
this is replicating dead fuels which is
typically on the ground what catches
easily on fire is the dead field this
one you see here with the leaves this is
our what we call the live view the live
fuels are collected locally so it’s very
important for us to study the specific
fuel here because it’s such a great
contributor to the wildfires that we get
in the region wind tunnel is
instrumented with a barrage of
instruments that includes
temperature probes or thermocouples heat
flux sensors relative humidity sensors
load cells that are measuring mass loss
of you were ready right away once our
computers are ready and our cameras all
ready we’re ready to ignite are we all
ready
nation our study wants to focus on
if the debt-fueled do catch fire through
lightning or cigarette butt or something
whether that will transition to the
actual live shrub once it gets to the
live strobe we want to know if it’s
gonna spread throughout the whole shrub
community today we are varying wind
speed in this applying more oxygen to
fire so fire can consume a fuels much
faster in experiments where we have in
fire is much more intense flame height
is much higher wind will help those
flames to be tilted which will enable
neighboring fuel to ignite faster eight
hundred fifteen hundred Fahrenheit we
worked with the Forest Service to
provide them information that they need
to manage the land
wind blowing this way you’ve got a flame
is the one able to go past this here in
California we have a condition called
Santa Ana winds which are high speed
winds which could cause destructive
fires wind is probably one of the most
important factors that affects fire
spread we’re modeling it to control as
much as we can so we can really
understand what the important variables
are down the road we hope to have a
perfect computer model that we simply
ask if ignition occurs in this part of a
forest under certain conditions what
will happen within the next 30 minutes
within one hour what would be the best
way to deploy resources global climate
change is gonna bring more wildfires
with greater intensity in areas like
Southern California in order to combat
them we need to understand them know how
to predict them
know how to fight them
