Fluid motion induced by surface tension variation is called the
Marangoni effect.
Fluid motion induced by surface tension variation is called the Marangoni effect Consider a liquid layer of thickness h on a solid flat plate. The liquid is exposed to ambient air but the surface tension σ is not constant. It varies longitudinally (in the x direction) due to a temperature gradient, which induces the liquid to move along the interface I. Write the governing equations for the liquid...
Problem 1 Consider a paper airplane that has a rubber band driven propeller. The equations of motion for it longitu dinal dynamics can be written as where its state vector is given by the velocity V and the flight path angle y, i.e., xV,E R2, and the control input is given by the thrust u. All of other variables, namely mass m, gravitational acceleration g, lift parameters I, and drag parameter d are fixed constants (a) Let V* > 0...
The heat that is conducted through a body must frequently be removed by other heat transfer processes. For example, the heat generated in an electronic device must be dissipated to the surroundings through convection by means of fins. Consider the one-dimensional aluminum fin (thickness t 3.0 mm, width 20 cm, length L) shown in Figure 1, that is exposed to a surrounding fluid at a temperature T. The conductivity of the aluminum fin (k) and coefficient of heat convection of...

Problem 2 (10 pt.) A homogeneous sphere of mass m and radius b is rolling on an inclined plane with inclination angle ? in the gravitational field g. Follow the steps below to find the velocity V of the center of mass of the sphere as a function of time if the sphere is initially at rest. Bold font represents vectors. There exists a reaction force R at the point of contact between the sphere and the plane. The equations...

PROJECT #1 (2.5 Marks): The heat that is conducted through a body must frequently be removed by other heat transter processes. For example, the heat generated in an electronic device must be dissipated to the surroundings through convection by means of fins.
