Effect of Different Nanofluids on Thermal Performance in Trapezoidal Corrugated Channel

Using corrugated channels is one of the passive heat transfer enhancement techniques in the fabrication of heat exchange devices. Designing more effective energy systems is a challenge for researchers and engineers to minimize the consumption of energy in order to improve energy system efficiency. In the present research, an experimental study of forced convective flows of different nanofluids through a trapezoidal corrugated channel at a constant wall temperature condition was performed. Numerical simulation of a corrugated channel was applied by using the nanofluid to probe the characteristics of the flow and thermal fields. For the purpose of solving the governing equations with corresponding boundary conditions, the finite volume method is employed by implementing the CFD commercial software ANSYS-FLUENT-V16. The channel was tested under a constant heat flux of 10 KW and the volume fraction of nanofluid is taken as 0.08. it was found that the pressure drop is found highest in the nanofluid tio2-water and is decreasing in the sequence is TiO2> SiO2>Fe2O3> Al2O3> ZnO> CuO.

Case Study

Ludwig’s Angina – Case Study

Ludwig's angina is extremely dangerous as it causes edema, distortion, and airway obstruction and can appear as a result of airway problems. The first phase of the management of patients with this disease is observation and intravenous antibiotics. Protecting the airway with surgical drainage will be the management of advanced diseases. In addition to this infection; pain, trismus, airway swelling, and tongue displacement lead to weak airways. Therefore, airway management is a major concern in these situations [1]. Although “normal” airway management for patients with deep neck disease is a tracheostomy with local anesthesia, in extreme cases the infection is difficult or sometimes not possible due to the required tracheostomy position or due to external neck distortion.

Review Paper

A Review on Effect of Different Nanofluids on Thermal Performance in Trapezoidal Corrugated Channel

Using corrugated channels is one of the passive heat transfer enhancement techniques in the fabrication of heat exchange devices. Designing more effective energy systems is a challenge for researchers and engineers to minimize the consumption of energy in order to improve energy system efficiency. In recent years, many industries have a strong need to achieve higher thermal performance in order to gain high efficiency, reduce the cost and weight, and minimize the size of heat exchangers. The use of corrugated channels can decrease the thermal resistance where it acts to reduce the thermal boundary layer thickness of the heat exchanger surface. Therefore, corrugated surface geometry is one of the numerous appropriate procedures to upgrade the heat transfer in these devices due to the appearance of the secondary flow regions in the trough of the corrugated channel which leads to improve the blending of the fluid and consequently maximize the heat transfer exchange. This paper presents the review of studies done by different researchers on the similar topic.

Mood recognition emotion ontology with texts

Emotion can be expressed in many ways where we can see recognition from speech, image or video frames, facial expression, gestures. Deep Learning has increasing attention to its significant processing power. The rapid development and universal availability of Social Media analyzing these data using traditional tools and technologies are tough to examine the fundamental behavior of occurrence in networking sites. Emotion detection in the text files is essentially content in social media. In this paper, we are seeing emotion recognition based on textual data and the techniques are the basic operation of arithmetic such as addition and statements of for loop, else if condition with deep learning and its features.

The effect of activities of daily living on depression among elderly people

Age is an important determinant of mental health. Depression creates the greatest burden among the elderly when compared to other mental disorders. Depression decreases an individual’s quality of life and increases dependence on others. A descriptive study to assess the effect of activities of daily living on depression among elderly people in selected community settings, Coimbatore. Methods: The study was conducted in the Vagarayanpalayam area of the community in Coimbatore, The sample size consists of 50 elderly aged between 60-80 years. Non-probability convenience sampling technique was used. The level of depression, the functional ability was assessed by using a modified geriatric depression scale, modified Barthel ADL index. Results: It was found that there is a significant association between depression and activities of daily living among elderly people at p<0.005. It was found that the calculated ANOVA test value for the study group,10.08 for the age group,25.88 for the gender,14.63 for the income was significantly associated with depression and activities of daily living at p<0.005 and not significant with other demographic variables. It was found that the calculated ANOVA test value for the study group,8.29 for the age group,24.03 for the gender,13.58 for the income was significantly associated with depression and activities of daily living at p<0.005 and not significant with other demographic variables.
