“…The suspended weights are tied with high tension cable cords that would withstand the weights when they move inside the shaft. These weights are as important as the shaft because they will be used to push the water downwards through the connecting pipeline and will move upwards when the water pressure difference causes it to move upwards [3,7].…”

Malaysia being an oil-producing country has a vast amount of other natural resources that has not been used efficiently. In regard to focusing more in producing oil and gas, natural resources such as sunlight, water, wind, geothermal and gravity have not received a huge recognition by the government. Although hydroelectric power has been up and coming in the energy policies to promote power production in a sustainable way, other means of gravity power generation mechanism were not reviewed for this country, due to the lack of knowledge in this particular field. Gravity power generation mechanism can be of small scale which can actually fit in properly in areas that are off-the-grid. Hence, literature must be reviewed to discover the different type of gravity power generation mechanisms and run viability studies to implement the right system that offers sustainable energy production in rural parts of Malaysia. This review paper will analyze the feasibility of two systems in Malaysia, by assessing the viability of these system through the Malaysian economic, social, environmental, and sustainable standards.

“…Flap type [7,8] and piston type [9,10] wave makers are commonly used to create waves. Yamac and Koca [11] have moved the wall using UDF in Ansys in order to generate waves. The waves created by these methods can be reflected back if the wave tank is not long enough.…”

Turbines are mechanical devices that convert fluid motion into rotational motion. In this study, water wave is used as fluid. Ansys Fluent's Volume Of Fluid (VOF) model is used and regular waves are obtained to analyze the movement of the turbine in the wave tank. The force, pressure, moment and speed of the turbine are important to obtain electrical energy from wave energy. For this reason, in this study, the change of these parameters with the effect of the wave is examined. It is observed that these parameter values increased with increasing wave height. It is observed that the dynamic pressure and moment of the turbine rise with the increase of the wavelength. However, the speed of rotation of the turbine decreased with the increase of the wavelength. The force coming to the blades did not change with the increase of the wavelength, it only caused a delay in time. However, it was observed that a very high force was applied to the turbine blades with a wave height of 2 m and this value reached 8000 N. In addition, the maximum turbine speed was obtained at a wavelength of 2 m and a wavelength of 20 m, reaching 87 mm / s.

“…Yayla et al [19] used a similar numerical strategy, embedding a piezoelectric generator behind vortex-generating plates involving nozzles of various angles and diameters in a single-phase turbulent flow channel. Yamac et al [20] simulated a wave tank by employing the moving mesh concept and the volumeof-fluid technique along with a code containing a similar methodology in Wu et al's article to assess the potency of fluid column height and waves height.…”

A fully-coupled-fluid-structure-piezoelectric model is presented based on the finite element method that is capable of modeling piezoelectric harvesters in the presence of free-surface flow and floating lightweight harvesters with arbitrary movements. The Navier-Stokes equations and the phase-field method are employed to describe the free-surface waves. Equations of the conservation of linear momentum in company with the piezoelectric constitutive relations in the strain-charge form are utilized to obtain solid deformation and the electric field intensity. According to the results, attaching mass to the tip of the beam leads to 13.5% rise in the output voltage compared to the state without the attached mass. Another studied factor was the influence of the load resistance on voltage and the output power. The generated voltage grows along with the load resistance until it reaches a constant value. However, the power has an optimum load resistance that is 2.61 times higher than the reference state. The beam's inclination is significant in effectively exploiting water waves due to raising the root mean square (RMS) value of the voltage by 89.53% at an angle of 40 degrees relative to the vertical state. By altering the thickness of the beam from 1 mm to the value of 1.5 mm, the RMS voltage exhibits a considerable upward change of 66%. By increasing the length of the cantilever beam connected to the buoyant structure, and therefore, the indentation of the beam in the water, the output voltage grows, such that a beam with the length of 25 cm shows a 2.92 times increase in the output voltage relative to the beam with a length of 15 cm.
