Abstract

A hot aluminum alloy AA6082 and nickel disc of 560 °C and 850 °C was cooled by a spray nozzle with the spray flux of 4.2, 10 and 13.7 kg/m2s. The temperature history during the cooling process was recorded with use of an infrared camera. The energy balance equation is the basis for the numerical procedure of Heat Transfer Coefficient (HTC) calculation in the film-boiling regime. It is found that HTC is almost independent from kind of metals. HTC has a stronger function of surface temperature. With use of single droplet model in film boiling developed, vapor film thickness can be calculated to predict this trend.

Abstract

The COVID-19 Pandemic changes people’s lifestyle nowadays. Physical interactions between person have lessened due to laws passed by central governments concerning its limitations. It’s no surprise this impacted businesses that needs face-to-face meetings, such as cafés or restaurants. Based on such facts, prototype for Automatic Café Management System (ACMS) based on Internet of Things (IOT) is designed. ACMS allows customers to order food through web-based system that can be accessed with their gadgets. The system is equipped with a line follower robot to act as waiter/waitress. With such system, physical contacts in café or restaurant settings can be reduced significantly.
