Chapter 12.3, Problem 12.21ACI

Bubble behavior in subcooled flow boiling. In industry cooling applications (e.g., cooling of nuclear reactors), a process called subcooled flow boiling is often employed. Subcooled flow boiling is susceptible to small bubbles that occur near the heated surface. The characteristics of these bubbles were investigated in Heat Transfer Engineering (Vol. 34., 2013). A series of experiments was conducted to measure two important bubble behaviors—bubble diameter (millimeters) and bubble density (liters per meters squared). The mass flux (kilograms per meters squared per second) and heat flux (megawatts per meters squared) were varied for each experiment. The data obtained at a set pressure are listed in the following table.

a. Consider the multiple regression model, E (y₁) = β_{0 +} β₁ x_{1 +} β₂x₂, where y₁ = bubble diameter, x₁ = mass flux, and x₂ = heat flux. Use statistical software to fit the model to the data and test the overall adequacy of the model.

b. Consider the multiple regression model, E(y₂) = β_{0 +} β₁ x_{1 +} β₂x₂, where y₂ = bubble density, x₁ = mass flux, and x₂ = heat flux. Use statistical software to fit the model to the data and test the overall adequacy of the model.

c. Which of the two dependent variables, diameter (y₁) or density (y₂). is better predicted by mass flux (x₁) and heat flux (x₂)?

An article in Technometrics (1974, Vol. 16, pp. 523–531) considered the following stack-loss data from a plant oxidizing ammonia to nitric acid. Twenty-one daily responses of stack loss (the amount of ammonia escaping) were measured with air flow x1, temperature x2, and acid concentration x3. y = 42, 37, 37, 28, 18, 18, 19, 20, 15, 14, 14, 13, 11, 12, 8, 7, 8, 8, 9, 15, 15 x1 = 80, 80, 75, 62, 62, 62, 62, 62, 58, 58, 58, 58, 58, 58, 50, 50, 50, 50, 50, 56, 70 x2 = 27, 27, 25, 24, 22, 23, 24, 24, 23, 18, 18, 17, 18, 19, 18, 18, 19, 19, 20, 20, 20 x3 = 89, 88, 90, 87, 87, 87, 93, 93, 87, 80, 89, 88, 82, 93, 89, 86, 72, 79, 80, 82, 91 (a) Fit a linear regression model relating the results of the stack loss to the three regressor variables.
