Modeling the 2-D temperature distribution of multiple lava dikes cooling over time
By Sky LovillSlide2
Modeled a set of
5 lava dikes with different initial
conditions cooling over 1 hour
Used 4 variables for initial conditions: width of dike, the temperature of lava in the dike, the width of host rock & the temperature of host rockThis model used the following discretized form of the differential equation, where the temperature of the rock at any point in the distribution is a function of x & tWhere the constant c = k/(cp*ρ) and:k=0.031 J/cm*s*K Heat conductance of lava & rock cp=1.1 J/g*K Heat capacity of lava ρ=2.65g/cm3 Density of rock & lava Slide3
Initial Conditions
Temperature of dikes start at 1300
°
C, and decrease by 100°C from left to right Temperature of host rock = 0°CRatios of host rock width to dike width = 2:1EXCEPTIONS: the middle dike is 2x the width of all other dikesThe host rock in between the 4th and 5th dikes (from the left) is ½ the width of the other host rockTemperature of host rock = 200°C on far rightSlide4
