Challenge Problems
Push your limits with challenges.
Question 1
Discuss how the properties of the stress tensor differ in extreme conditions, such as in high-speed flows. What complications could arise in these scenarios?
💡 Hint: Consider how physical laws change when conditions are extreme.
Question 2
Analyze a practical scenario involving the flow of blood (a non-Newtonian fluid). How does its behavior challenge traditional fluid dynamics modeling?
💡 Hint: Think about how blood flow differs compared to water.
