Analyzing Airflow Patterns in a Warehouse Ventilation System

You are helping design an air circulation system for a large distribution warehouse. The warehouse floor can be modeled as a coordinate plane, where distances are measured in meters from a central reference point. The HVAC engineering team has provided you with mathematical models of different airflow patterns they are considering. Your task is to analyze these velocity fields to understand how air moves through the space, identify what type of circulation pattern each model creates, and determine whether certain airflow configurations can be described using a potential function. This analysis will help the team select the most effective ventilation design for maintaining air quality and temperature control throughout the facility.
