What is the impact of wind speed on ventilation efficiency of a solar chimney?

Project Location: Zone 0A Extremely Hot Humid

Simulation Scale: Whole Building

Application: Research

Audience: Academic

What is this graphic showing? Describe the different parts of the graphic and how it communicates the data.

The space has an evaporative brick mass wall that is at 24°C wet bulb temperature in 40°C Ambient air temperature receiving wind from the West facade that facilitates the evaporative cooling to travel inside the space, increasing the efficiency of the solar chimney. The graphic articulates more cooling inside the space at higher wind speeds.

What type of graphic is this?

  • Animated gif

Design Variables

  • Passive strategies

Is this part of the ASHRAE-209 cycle?

What tools were used for the simulation analysis?

  • Computational Fluid Dynamics
  • Other

What tools did you use to create the graphic?

  • Grasshopper/Rhino
  • Other
  • PowerPoint

What was successful and/or unique about the graphic in how it communicates information?

It shows Temperature and velocity charts in juxtaposition to clearly articulate that there is more cooling inside the space at higher wind speeds.

Is there anything else you would like to mention?

The tool used for the analysis was RhinoCFD.
