Question
You are employed as a mechanical engineer within an unnamed research center, specializing in the development
of innovative air conditioning systems. Your division is tasked with providing computer-based modeling and
design solutions using computational fluid dynamics through ANSYS software. Your primary responsibilities
involve the analysis of horizontal channel dynamics to meet specific criteria. Under the guidance of your
immediate supervisor, you have been assigned unique responsibilities within an ongoing project. As a member of
the research team, your role includes constructing an appropriate model and executing a sequence of simulation
iterations to explore and enhance channel performance. Figure 1 provides a visualization of the horizontal channel
under consideration. Consider 2D, incompressible, steady flow in a horizontal channel at a Reynolds number of
150. The schematic below illustrates the channel flow, not drawn to scale. For simplicity, neglect gravity. The
channel's length and width are 15 m and 1.5 m, respectively, as shown in the figure. Assume the thickness is equal
to 1.5 m in the z-direction. The velocity is constant at the inlet in the x-direction and equal to 1.5 m/s. The Reynolds
number is defined as Re = where v is the average velocity. Take p = 1.2 kg/m³ and adjust u to get the
desired Reynolds number. The absolute pressure at the outlet is 1 atm.

You need to solve the 2D form of the governing equations using ANSYS Fluent to obtain the velocity and pressure
distribution in the xy plane. Since we are assuming the flow is 2D, the mathematical model to be solved is 2D and
there is no variation of velocity and pressure in the z-direction.
