Title : Nasal Airflow Simulation on Healthy Child using Computational Fluid Dynamics

Abstract :

This research examines the influence of age on healthy child nasal airflow along the entire nasal cavity. In this research, a nasal airflow simulation is performed on a Malaysian 5-years-old female child via computational fluid dynamics (CFD). The Malaysia female child model exhibits narrower and thinner nasal passageway and has shorter turbinate’s region as compared with the other two models, i.e., male child model and female adult model from previous works. Despite their differences, a general trend is still visible in terms of cross-sectional area and average velocity magnitude profiles of the airways along with the axial distance. Besides, pressure drop, which is also known as the breathing resistance, was found to decrease as the age increases. It is also worth noticing that the flow field in the nasal cavity of a child tends to concentrate centrally when the airstream develops.

Title : Flexible based Piezoelectric Ultrasonic Transducer with Air Backing for Wideband High-Frequency Underwater Ultrasonic Applications

Abstract :

High-frequency ultrasonic transducer has been used in an underwater non-destructive application, underwater acoustic imaging, and high-frequency sonar. Normally, all these applications need a high-resolution transducer. For this reason, the transducer must be a high-resolution transducer subsequently, the transducer must be a good receiving sensitivity and wide bandwidth. In this paper, a flexible piezoelectric ultrasonic transducer (FPUT) was designed and characterized in an open-circuit receiving response for underwater application. The target operating frequency is a high-frequency ultrasonic range between 25 kHz to 1.5 MHz for an acoustic transducer. Polyimide is used as a flexible substrate for the cover layer and the flexible circuit. The electrodes for positive potential and ground were designed in a lateral structure whereby this design can improve the receiving sensitivity. A Polyvinylidene fluoride (PVDF) film was functioning as a sensing element and placed on the top of an electrode. A polyimide layer is used as it is a semipermeable membrane manufactured principally for use in water purification or water desalination systems. A 3M tape was used as a matching layer interface between water and PVDF. The air backing was used as a signal absorber to expand the frequency bandwidth. The pulse-echo method is used to characterize the sensitivity of ultrasonic transducer in underwater. The receiving sensitivity and frequency bandwidth are two important parameters to describe the electro-acoustic energy conversion efficiency of an ultrasonic transducer. An FPUT has a receiving sensitivity of -25.1827 dB rel 1 V/µPa dB with a resonance frequency of 425 kHz. The frequency bandwidth of this FPUT is 61.2%. This can conclude that a FPUT with air backing is capable to be a high receiving sensitivity ultrasonic transducer and wide frequency bandwidth for high-frequency ultrasonic applications
