Abstract: | Flow measurement has achieved huge strides in the last few decades. This phenomenon is a source that stimulates new applications. Performing an airflow measurement in logistic containers to maintain quality of sensitive products is one of these up-to-date applications. This thesis has two main objectives: First, to prove the suitability of thermal flow sensors for accurate airflow measurements. Second objective is to perform measurements and simulations in order to understand the convective transport inside reefer containers and improve the cooling system efficiency. On the sensor side, basic research studies were performed, including modeling, characterization, calibration, and integration in wireless measurement system. On the application side, several airflow field tests were conducted. Moreover, a simulation model was developed. Experimental results supported the simulation results, wherein both give a good understanding of the airflow and convective transport in the container. |
