在这项研究中，两个样品的棕榈油进行了研究，相对于温度对棕榈油样品的流变性能的影响。被调查的油类型为特种棕榈油和工业棕榈油。实验结果表明，棕榈油样品具有非牛顿流体的剪切变稀特性，其粘度、剪切应力和剪切速率等流变特性受温度的影响。油样的粘度随着温度的升高而降低，油样的粘度变化与油样的纯度有关。纯度还取决于油样的制备方法。当剪切应力与剪切速率呈线性关系时，在低剪切速率下发生牛顿行为。而在较高剪切速率下，粘度随剪切速率的增大而减小，即剪切变稀。
In this research, two samples of palm oil were studied with respect to the effect of temperature on the rheological properties of the palm oil samples. The types of oils under investigation were special palm oil and technical palm oil. It was observed that the palm oil samples exhibit shear thinning property as a non-Newtonian fluid and its rheological properties like viscosity, shear stress and shear rate were affected by temperature as indicated on the experimental result. The viscosity of the oil samples were observed to decrease with increasing temperature, it was also observed that the variation of the viscosity of the oil samples could be attributed to the degree of purity of the oil samples. The degree of purity also depends on the method of preparation of the oil samples. Newtonian behavior occurs at low shear rate when the shear stress and shear rate relationship is linear. While at higher shear rate, the viscosity decreases as the shear rate increases which is called shear thinning.
