Abstract null null The austenitic stainless-steel biomaterial, AISI 316L stainless steel, is one of the most widely used for orthopedic or prosthetic implant devices because it is easy to manufacture at a relatively low cost. However, corrosion is a challenging issue related to major alloying compounds with body fluids and wear. Therefore, this study aimed to develop a biomaterial of Fe–Al–Mn alloys by minimizing chromium (Cr) and nickel (Ni) contents. In the research, an attempt has been made t...

Abstract The processing of waste oil into diesel-like fuel (DLF) is a challenging issue related to waste management and energy supply. This paper describes an experimental study of compression ignition (CI) engine using blended fuel between diesel and distillation product of used-waste oil. The objective is to evaluate the engine performance and smoke opacity caused by waste-derived fuel (WDF). Using an unmodified CI engine, pure distillation product and blends with diesel were applied to evalua...

This study aims to investigate experimentally and numerically the characteristics of the NACA 24112 airfoil. This study focuses on investigations of lift coefficient ( C L ), drag coefficient (CD), and C L / C D ratio and pressure, including flow visualisation around the airfoil. The study was conducted at an angle of attack ranging to -15°-20° and various Mach number at 0.0728 and 0.0809. The experimental test used a test specimen with a span dimension of 20 cm and a chord of 10 cm with an open...

The braking process is the basis in the making of the PWM speed control system in order for electric cars to be able to stop automatically and increase the driving safety. The usage of an electric motor as a wheel drive for an electric car allows controlling with a microcontroller. Based on the journal about electric motor control, it is necessary to study the use of PWM as a speed controller. The C language as a coding language can be understood by the Arduino microcontroller with the aim of re...

Greenery systems are sustainable ecosystems for buildings. Many studies on greenery systems, such as green roofs and green walls, have demonstrated that greenery systems support energy saving and improve thermal conditions in the building sector. This paper summarizes, discusses, and compares greenery systems and their contributions to the reduction of the urban heat index, the reduction of internal and external buildings’ wall temperatures, and the reduction of the energy consumption of buildin...

Abstract Detached eddy simulation (DES) has been carried out to study a three-dimensional trailing-edge (TE) cutback turbine blade model with five rows of staggered circular pin-fin arrays inside the cooling passage, in order to evaluate the cooling performance in relation to coolant ejection slot angle. Simulations were performed by adopting a shear-stress transport k-ω turbulence model, and the effects of three different ejection slot angles 5°, 10° and 15° were investigated in terms of the ch...

Sunlight is an environmentally friendly energy source, which has great potential for use as an alternative renewable energy source in overcoming the energy crisis in the future, mainly in tropical countries. This paper presents an automatic solar tracking system that uses Arduino UNO to demonstrate the production of daytime energy from sunlight. A small prototype with the ability to rotate up to 180 degrees on the horizontal and vertical axes has been successfully fabricated in order to realise ...
