Challenge Problems
Push your limits with advanced challenges
Consider a concrete slab with modified initial temperature distribution given by $$u(x,0) = 50 + 20 ext{sin}igg( rac{5 ext{π}x}{10}igg)$$. Determine the steady-state temperature profile as time approaches infinity.
💡 Hint: Focus on how oscillating functions behave as they dissipate energy.
If the thermal diffusivity, α, changes to 0.5, analyze how this affects the decay time of the temperature wave.
💡 Hint: Think about how thermal properties influence heat behavior.
