You are employed as a mechanical engineer within an unnamed research center, specializing in the development of innovative air conditioning systems.

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.
